After commit 9298e63eaf ("bpf/tests: Add exhaustive tests of ALU
operand magnitudes"), when modprobe test_bpf.ko with JIT on mips64,
there exists segment fault due to the following reason:
[...]
ALU64_MOV_X: all register value magnitudes jited:1
Break instruction in kernel code[#1]
[...]
It seems that the related JIT implementations of some test cases
in test_bpf() have problems. At this moment, I do not care about
the segment fault while I just want to verify the test cases of
tail calls.
Based on the above background and motivation, add the following
module parameter test_suite to the test_bpf.ko:
test_suite=<string>: only the specified test suite will be run, the
string can be "test_bpf", "test_tail_calls" or "test_skb_segment".
If test_suite is not specified, but test_id, test_name or test_range
is specified, set 'test_bpf' as the default test suite. This is useful
to only test the corresponding test suite when specifying the valid
test_suite string.
Any invalid test suite will result in -EINVAL being returned and no
tests being run. If the test_suite is not specified or specified as
empty string, it does not change the current logic, all of the test
cases will be run.
Here are some test results:

Add preliminary support for the Surface Pro 8 to the Surface Aggregator
registry. This includes battery/charger status and platform profile
support.
In contrast to earlier Surface Pro generations, the keyboard cover is
now also connected via the Surface Aggregator Module (whereas it was
previously connected via USB or HID-over-I2C). To properly support the
HID devices of that cover, however, more changes regarding hot-removal
of Surface Aggregator client devices as well as a new device hub driver
are required. We will address those things in a follow-up series, so do
not add any HID device IDs just yet.

When we receive an association response, a significant amount
of time might have passed since we sent the corresponding
association request (mac80211 will wait up to 500ms for the TX

the time event is touched only when we send the assoc request,
so it might not have much time remaining, more easily causing

Trying to convert from one firmware data representation to the
next version is getting tedious and error-prone, and doesn't
lend itself well to new APIs being added. Additionally, the
version 11 of the API as defined in the driver doesn't even
exist in the firmware.
Instead of converting to a newer firmware version of the data,
convert to an internal representation. This takes a bit more
space because the TKIP/AES counters etc. must be kept twice,
their representation is different and we don't know which of
the ones it is until later, but this is just a temporary use
of memory, and the code is clearer this way.

Add flag returned by FUSE_OPEN and FUSE_CREATE requests to avoid flushing
data cache on close.
Different filesystems implement ->flush() is different ways:
- Most disk filesystems do not implement ->flush() at all
- Some network filesystem (e.g. nfs) flush local write cache of
FMODE_WRITE file and send a "flush" command to server
- Some network filesystem (e.g. cifs) flush local write cache of
FMODE_WRITE file without sending an additional command to server
FUSE flushes local write cache of ANY file, even non FMODE_WRITE
and sends a "flush" command to server (if server implements it).
The FUSE implementation of ->flush() seems over agressive and
arbitrary and does not make a lot of sense when writeback caching is
disabled.
Instead of deciding on another arbitrary implementation that makes
sense, leave the choice of per-file flush behavior in the hands of
the server.

If writeback_cache is enabled, then the size, mtime and ctime attributes of
regular files are always valid in the kernel's cache. They are retrieved
from userspace only when the inode is freshly looked up.

In case of writeback_cache fuse_fillattr() would revert the queried
attributes to the cached version.
Move this to fuse_change_attributes() in order to manage the writeback
logic in a central helper. This will be necessary for patches that follow.
Only fuse_do_getattr() -> fuse_fillattr() uses the attributes after calling
fuse_change_attributes(), so this should not change behavior.

It's safe to call file_update_time() if writeback cache is not enabled,
since S_NOCMTIME is set in this case. This part is purely a cleanup.
__fuse_copy_file_range() also calls fuse_write_update_attr() only in the
writeback cache case. This is inconsistent with other callers, where it's
called unconditionally.

This has already been done in all cases except in fuse_notify_store(), so

The attribute version in fuse_inode should be updated whenever the
attributes might have changed on the server. In case of cached writes this
is not the case, so updating the attr_version is unnecessary and could
possibly affect performance.

Only invalidate attributes that the operation might have changed.

The fuse_iget() call in create_new_entry() already updated the inode with
all the new attributes and incremented the attribute version.
Incrementing the nlink will result in the wrong count. This wasn't noticed
because the attributes were invalidated right after this.
Updating ctime is still needed for the writeback case when the ctime is not
refreshed.
