mm: khugepaged: don't carry huge page to the next loop for !CONFIG_NUMA
Patch series "mm: userspace hugepage collapse", v7.
Introduction
--------------------------------
This series provides a mechanism for userspace to induce a collapse of
eligible ranges of memory into transparent hugepages in process context,
thus permitting users to more tightly control their own hugepage
utilization policy at their own expense.
This idea was introduced by David Rientjes[5].
Interface
--------------------------------
The proposed interface adds a new madvise(2) mode, MADV_COLLAPSE, and
leverages the new process_madvise(2) call.
process_madvise(2)
Performs a synchronous collapse of the native pages
mapped by the list of iovecs into transparent hugepages.
This operation is independent of the system THP sysfs settings,
but attempts to collapse VMAs marked VM_NOHUGEPAGE will still fail.
THP allocation may enter direct reclaim and/or compaction.
When a range spans multiple VMAs, the semantics of the collapse
over of each VMA is independent from the others.
Caller must have CAP_SYS_ADMIN if not acting on self.
Return value follows existing process_madvise(2) conventions. A
“success” indicates that all hugepage-sized/aligned regions
covered by the provided range were either successfully
collapsed, or were already pmd-mapped THPs.
madvise(2)
Equivalent to process_madvise(2) on self, with 0 returned on
“success”.
Current Use-Cases
--------------------------------
(1) Immediately back executable text by THPs. Current support provided
by CONFIG_READ_ONLY_THP_FOR_FS may take a long time on a large
system which might impair services from serving at their full rated
load after (re)starting. Tricks like mremap(2)'ing text onto
anonymous memory to immediately realize iTLB performance prevents
page sharing and demand paging, both of which increase steady state
memory footprint. With MADV_COLLAPSE, we get the best of both
worlds: Peak upfront performance and lower RAM footprints. Note
that subsequent support for file-backed memory is required here.
(2) malloc() implementations that manage memory in hugepage-sized
chunks, but sometimes subrelease memory back to the system in
native-sized chunks via MADV_DONTNEED; zapping the pmd. Later,
when the memory is hot, the implementation could
madvise(MADV_COLLAPSE) to re-back the memory by THPs to regain
hugepage coverage and dTLB performance. TCMalloc is such an
implementation that could benefit from this[6]. A prior study of
Google internal workloads during evaluation of Temeraire, a
hugepage-aware enhancement to TCMalloc, showed that nearly 20% of
all cpu cycles were spent in dTLB stalls, and that increasing
hugepage coverage by even small amount can help with that[7].
(3) userfaultfd-based live migration of virtual machines satisfy UFFD
faults by fetching native-sized pages over the network (to avoid
latency of transferring an entire hugepage). However, after guest
memory has been fully copied to the new host, MADV_COLLAPSE can
be used to immediately increase guest performance. Note that
subsequent support for file/shmem-backed memory is required here.
(4) HugeTLB high-granularity mapping allows HugeTLB a HugeTLB page to
be mapped at different levels in the page tables[8]. As it's not
"transparent" like THP, HugeTLB high-granularity mappings require
an explicit user API. It is intended that MADV_COLLAPSE be co-opted
for this use case[9]. Note that subsequent support for HugeTLB
memory is required here.
Future work
--------------------------------
Only private anonymous memory is supported by this series. File and
shmem memory support will be added later.
One possible user of this functionality is a userspace agent that
attempts to optimize THP utilization system-wide by allocating THPs
based on, for example, task priority, task performance requirements, or
heatmaps. For the latter, one idea that has already surfaced is using
DAMON to identify hot regions, and driving THP collapse through a new
DAMOS_COLLAPSE scheme[10].
This patch (of 17):
The khugepaged has optimization to reduce huge page allocation calls for
!CONFIG_NUMA by carrying the allocated but failed to collapse huge page to
the next loop. CONFIG_NUMA doesn't do so since the next loop may try to
collapse huge page from a different node, so it doesn't make too much
sense to carry it.
But when NUMA=n, the huge page is allocated by khugepaged_prealloc_page()
before scanning the address space, so it means huge page may be allocated
even though there is no suitable range for collapsing. Then the page
would be just freed if khugepaged already made enough progress. This
could make NUMA=n run have 5 times as much thp_collapse_alloc as NUMA=y
run. This problem actually makes things worse due to the way more
pointless THP allocations and makes the optimization pointless.
This could be fixed by carrying the huge page across scans, but it will
complicate the code further and the huge page may be carried indefinitely.
But if we take one step back, the optimization itself seems not worth
keeping nowadays since:
* Not too many users build NUMA=n kernel nowadays even though the kernel is
actually running on a non-NUMA machine. Some small devices may run NUMA=n
kernel, but I don't think they actually use THP.
* Since commit

bitmap fixes for v6.0-rc3
Hi Linus, Please pull (hopefully) the last portion of fixes from Sander for his UP rework series. The original series came from -mm tree, and it was not the latest version, that's why we need follow-ups. It fixes only a test introduced by that series. The test fails under certain configs. From Sander: This series fixes the reported issues, and implements the suggested improvements, for the version of the cpumask tests [1] that was merged with commit |

mm/damon/dbgfs: avoid duplicate context directory creation
When user tries to create a DAMON context via the DAMON debugfs interface
with a name of an already existing context, the context directory creation
fails but a new context is created and added in the internal data
structure, due to absence of the directory creation success check. As a
result, memory could leak and DAMON cannot be turned on. An example test
case is as below:
# cd /sys/kernel/debug/damon/
# echo "off" > monitor_on
# echo paddr > target_ids
# echo "abc" > mk_context
# echo "abc" > mk_context
# echo $$ > abc/target_ids
# echo "on" > monitor_on <<< fails
Return value of 'debugfs_create_dir()' is expected to be ignored in
general, but this is an exceptional case as DAMON feature is depending
on the debugfs functionality and it has the potential duplicate name
issue. This commit therefore fixes the issue by checking the directory
creation failure and immediately return the error in the case.

asm-generic: sections: refactor memory_intersects
There are two problems with the current code of memory_intersects: First, it doesn't check whether the region (begin, end) falls inside the region (virt, vend), that is (virt < begin && vend > end). The second problem is if vend is equal to begin, it will return true but this is wrong since vend (virt + size) is not the last address of the memory region but (virt + size -1) is. The wrong determination will trigger the misreporting when the function check_for_illegal_area calls memory_intersects to check if the dma region intersects with stext region. The misreporting is as below (stext is at 0x80100000): WARNING: CPU: 0 PID: 77 at kernel/dma/debug.c:1073 check_for_illegal_area+0x130/0x168 DMA-API: chipidea-usb2 e0002000.usb: device driver maps memory from kernel text or rodata [addr=800f0000] [len=65536] Modules linked in: CPU: 1 PID: 77 Comm: usb-storage Not tainted 5.19.0-yocto-standard #5 Hardware name: Xilinx Zynq Platform unwind_backtrace from show_stack+0x18/0x1c show_stack from dump_stack_lvl+0x58/0x70 dump_stack_lvl from __warn+0xb0/0x198 __warn from warn_slowpath_fmt+0x80/0xb4 warn_slowpath_fmt from check_for_illegal_area+0x130/0x168 check_for_illegal_area from debug_dma_map_sg+0x94/0x368 debug_dma_map_sg from __dma_map_sg_attrs+0x114/0x128 __dma_map_sg_attrs from dma_map_sg_attrs+0x18/0x24 dma_map_sg_attrs from usb_hcd_map_urb_for_dma+0x250/0x3b4 usb_hcd_map_urb_for_dma from usb_hcd_submit_urb+0x194/0x214 usb_hcd_submit_urb from usb_sg_wait+0xa4/0x118 usb_sg_wait from usb_stor_bulk_transfer_sglist+0xa0/0xec usb_stor_bulk_transfer_sglist from usb_stor_bulk_srb+0x38/0x70 usb_stor_bulk_srb from usb_stor_Bulk_transport+0x150/0x360 usb_stor_Bulk_transport from usb_stor_invoke_transport+0x38/0x440 usb_stor_invoke_transport from usb_stor_control_thread+0x1e0/0x238 usb_stor_control_thread from kthread+0xf8/0x104 kthread from ret_from_fork+0x14/0x2c Refactor memory_intersects to fix the two problems above.

mm/zsmalloc: do not attempt to free IS_ERR handle
zsmalloc() now returns ERR_PTR values as handles, which zram accidentally
can pass to zs_free(). Another bad scenario is when zcomp_compress()
fails - handle has default -ENOMEM value, and zs_free() will try to free
that "pointer value".
Add the missing check and make sure that zs_free() bails out when
ERR_PTR() is passed to it.

writeback: avoid use-after-free after removing device
When a disk is removed, bdi_unregister gets called to stop further
writeback and wait for associated delayed work to complete. However,
wb_inode_writeback_end() may schedule bandwidth estimation dwork after
this has completed, which can result in the timer attempting to access the
just freed bdi_writeback.
Fix this by checking if the bdi_writeback is alive, similar to when
scheduling writeback work.
Since this requires wb->work_lock, and wb_inode_writeback_end() may get
called from interrupt, switch wb->work_lock to an irqsafe lock.

If we do end up in this code path, we store the wrong page in the shmem

provide arch_test_bit_acquire for architectures that define test_bit
Some architectures define their own arch_test_bit and they also need
arch_test_bit_acquire, otherwise they won't compile. We also clean up
the code by using the generic test_bit if that is equivalent to the
arch-specific version.

perf record: Fix manpage formatting of description of support to hybrid systems
The Intel hybrid description is written in a different style than the rest of the perf record man page. There were some new command line options added after it which resulted in very strange section ordering. Move the hybrid include last. Also the sub sections in the hybrid document don't fit the record manpage well (especially since it talks about all kinds of unrelated commands). I left this for now, but would be better to separate this properly in the different man pages. It would be better to use sub sections for the other sections, but these don't seem to be supported in AsciiDoc? Some of the examples are still misrendered in the manpage with an indented troff command, but I don't know how to fix that. In any case it's now better than before.

perf stat: Clear evsel->reset_group for each stat run
If a weak group is broken then the reset_group flag remains set for
the next run. Having reset_group set means the counter isn't created
and ultimately a segfault.
A simple reproduction of this is:
# perf stat -r2 -e '{cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles,cycles}:W
which will be added as a test in the next patch.

perf python: Fix build when PYTHON_CONFIG is user supplied
The previous change to Python autodetection had a small mistake where the auto value was used to determine the Python binary, rather than the user supplied value. The Python binary is only used for one part of the build process, rather than the final linking, so it was producing correct builds in most scenarios, especially when the auto detected value matched what the user wanted, or the system only had a valid set of Pythons. Change it so that the Python binary path is derived from either the PYTHON_CONFIG value or PYTHON value, depending on what is specified by the user. This was the original intention. This error was spotted in a build failure an odd cross compilation environment after commit |
