For some unknown reason, when I converted the incore dquot objects to
store the dquot id in host endian order, I removed the increment here.
This causes the scan to stop after retrieving the root dquot, which
severely limits the usefulness of the quota scrubber. Fix the lost
increment, though it won't fix the problem that the quota iterator code
filters out zeroed dquot records.

Before we start adding online repair functionality, there's a few tweaks
that I'd like to make to the common repair code. First is a fix to the
integration between repair and the health status code that was
interfering with repair re-evaluations. Second is a minor tweak to the
sole existing repair functions to make one last check that the user
hasn't terminated the calling process before we start writing to the
filesystem. This is a pattern that will repeat throughout the rest of
the repair functions.

This series introduces simple usage and performance counters for the
online fsck subsystem. The goal here is to enable developers and
sysadmins to look at summary counts of how many objects were checked and
repaired; what the outcomes were; and how much time the kernel has spent
on these operations. The counter file is exposed in debugfs because
that's easier than cramming it into the device model, and debugfs
doesn't have rules against complex file contents, unlike sysfs.

In general, online repair of an indexed record set walks the filesystem
looking for records. These records are sorted and bulk-loaded into a
new btree. To make this happen without pinning gigabytes of metadata in
memory, first create an abstraction ('xfile') of memfd files so that
kernel code can access paged memory, and then an array abstraction
('xfarray') based on xfiles so that online repair can create an array of
new records without pinning memory.
These two data storage abstractions are critical for repair of space
metadata -- the memory used is pageable, which helps us avoid pinning
kernel memory and driving OOM problems; and they are byte-accessible
enough that we can use them like (very slow and programmatic) memory
buffers.
Later patchsets will build on this functionality to provide blob storage
and btrees.

These patches fix a few problems that I noticed in the code that deals
with old btree blocks after a successful repair.
First, I observed that it is possible for repair to incorrectly
invalidate and delete old btree blocks if they were crosslinked. The
solution here is to consult the reverse mappings for each block in the
extent -- singly owned blocks are invalidated and freed, whereas for
crosslinked blocks, we merely drop the incorrect reverse mapping.
A largeish change in this patchset is moving the reaping code to a
separate file, because the code are mostly interrelated static
functions. For now this also drops the ability to reap file blocks,
which will return when we add the bmbt repair functions.
Second, we convert the reap function to use EFIs so that we can commit
to freeing as many blocks in as few transactions as we dare. We would
like to free as many old blocks as we can in the same transaction that
commits the new structure to the ondisk filesystem to minimize the
number of blocks that leak if the system crashes before the repair fully
completes.
The third change made in this series is to avoid tripping buffer cache
assertions if we're merely scanning the buffer cache for buffers to
invalidate, and find a non-stale buffer of the wrong length. This is
primarily cosmetic, but makes my life easier.
The fourth change restructures the reaping code to try to process as many
blocks in one go as possible, to reduce logging traffic.
The last change switches the reaping mechanism to use per-AG bitmaps
defined in a previous patchset. This should reduce type confusion when
reading the source code.
This has been running on the djcloud for years with no problems. Enjoy!

Parse the device tree in early init to find the memory block size to be
used by the kernel. Consolidate the memory block size device tree parsing
to one helper and use that on both powernv and pseries. We still want to
use machine-specific callback because on all machine types other than
powernv and pseries we continue to return MIN_MEMORY_BLOCK_SIZE.
pseries_memory_block_size used to look for the second memory
block (memory@x) to determine the memory_block_size value. This patch
changed that to look at all memory blocks and make sure we can map them all
correctly using the computed memory block size value.
Add workaround to force 256MB memory block size if device driver managed
memory such as GPU memory is present. This helps to add GPU memory
that is not aligned to 1G.

I do not choose to continue as maintainer.
My final act as maintainer is to write down every thing that I've been
doing as maintainer for the past six years. There are too many demands
placed on the maintainer, and the only way to fix this is to delegate
the responsibilities. I also wrote down my impressions of the unwritten
rules about how to contribute to XFS.
The patchset concludes with my nomination for a new release manager to
keep things running in the interim. Testing and triage; community
management; and LTS maintenance are all open positions.
I'm /continuing/ as a senior developer and reviewer for XFS. I expect
to continue participating in interlock calls, LSFMM, etc.
v2: clarify release manager role, amend some factual errors, add some
acks and reviews.
v3: add more review tags.
With a bit of luck, this should all go splendidly.

Currently for testing an output format with DSC, we just force the
output format, without checking if it can be supported.
This also creates an issue where there is a PCON which might need to
convert from forced output format to the format to sink format.

Currently, we take the max lane, rate and pipe bpp, to get the maximum
compressed bpp possible. We then set the output bpp to this value.
This patch provides support to have max bpp, min rate and min lanes,
that can support the min compressed bpp.

-Avoid ending up with compressed bpp, same as pipe bpp. (Stan)
-Fix the checks for limits->max/min_bpp while iterating over list of
valid DSC bpcs. (Stan)
v3:
-Refactor the code to have pipe bpp/compressed bpp computation and slice
count calculation separately for different cases.
v4:
-Separate the pipe_bpp calculation for eDP and DP.
v5:
-Get rid of magic numbers for max and min bpp,
and improve documentation. (Stan).
-Use functions for {src_sink}_{min_max}_compressed_bpp (Ville).
v6:
-Remove lines to set link config to max.
v7:
-Split the part to separate edp and dp functions for computing DSC BPP
into separate patch.
v8:
-Separate mechanism to get compressed bpp for ICL,TGL and XELPD+.

Check this condition for cases where bpc is forced by debugfs flag
