    7413ab70 · bcachefs: Refactor memcpy into direct assignment · 
    Initial bcachefs pull request for 6.7-rc1

Here's the bcachefs filesystem pull request.

Testing - fstests as well as the bcachefs specific tests in ktest:
  https://evilpiepirate.org/~testdashboard/ci?branch=bcachefs-for-upstream

It's also been soaking in linux-next, which resulted in a whole bunch of
smatch complaints and fixes and a patch or two from Kees.

The only new non fs/bcachefs/ patch is the objtool patch that adds
bcachefs functions to the list of noreturns. The patch that exports
osq_lock() has been dropped for now, per Ingo.

Prereq patch list:

    2d5f216b · xfs: convert rt extent numbers to xfs_rtxnum_t · 
    xfs: clean up realtime type usage [v1.1]

The realtime code uses xfs_rtblock_t and xfs_fsblock_t in a lot of
places, and it's very confusing.  Clean up all the type usage so that an
xfs_rtblock_t is always a block within the realtime volume, an
xfs_fileoff_t is always a file offset within a realtime metadata file,
and an xfs_rtxnumber_t is always a rt extent within the realtime volume.

v1.1: various cleanups suggested by hch

With a bit of luck, this should all go splendidly.

    xfs: refactor rt extent unit conversions [v1.1]

This series replaces all the open-coded integer division and
multiplication conversions between rt blocks and rt extents with calls
to static inline helpers.  Having cleaned all that up, the helpers are
augmented to skip the expensive operations in favor of bit shifts and
masking if the rt extent size is a power of two.

    xfs: refactor rtbitmap/summary accessors [v1.2]

Since the rtbitmap and rtsummary accessor functions have proven more
controversial than the rest of the macro refactoring, split the patchset
into two to make review easier.

v1.1: various cleanups suggested by hch
v1.2: rework the accessor functions to reduce the amount of cursor
      tracking required, and create explicit bitmap/summary logging
      functions

Soon we'll be needing to add more complex logic to the helpers.

    e0f7422f · xfs: don't look for end of extent further than necessary in xfs_rtallocate_extent_near() · 
    xfs: CPU usage optimizations for realtime allocator [v2.3]

This is version 2 of [Omar's] XFS realtime allocator opimization patch
series.

Changes since v1 [1]:

- Fixed potential overflow in patch 4.
- Changed deprecated typedefs to normal struct names
- Fixed broken indentation
- Used xfs_fileoff_t instead of xfs_fsblock_t where appropriate.
- Added calls to xfs_rtbuf_cache_relse anywhere that the cache is used
  instead of relying on the buffers being dirtied and thus attached to
  the transaction.
- Clarified comments and commit messages in a few places.
- Added Darrick's Reviewed-bys.

Cover letter from v1:

Our distributed storage system uses XFS's realtime device support as a
way to split an XFS filesystem between an SSD and an HDD -- we configure
the HDD as the realtime device so that metadata goes on the SSD and data
goes on the HDD.

We've been running this in production for a few years now, so we have
some fairly fragmented filesystems. This has exposed various CPU
inefficiencies in the realtime allocator. These became even worse when
we experimented with using XFS_XFLAG_EXTSIZE to force files to be
allocated contiguously.

This series adds several optimizations that don't change the realtime
allocator's decisions, but make them happen more efficiently, mainly by
avoiding redundant work. We've tested these in production and measured
~10%% lower CPU utilization. Furthermore, it made it possible to use
XFS_XFLAG_EXTSIZE to force contiguous allocations -- without these
patches, our most fragmented systems would become unresponsive due to
high CPU usage in the realtime allocator, but with them, CPU utilization
is actually ~4-6%% lower than before, and disk I/O utilization is 15-20%%
lower.

Patches 2 and 3 are preparations for later optimizations; the remaining
patches are the optimizations themselves.

v2.1: djwong rebased everything atop his own cleanups, added dave's rtalloc_args
v2.2: rebase with new apis and clean them up too
v2.3: move struct definition around for lolz

With a bit of luck, this should all go splendidly.
