Merge tag 'bcachefs-
2024-05- 19' of https:/ /evilpiepirate. org/git/ bcachefs Pull bcachefs updates from Kent Overstreet:
- More safety fixes, primarily found by syzbot
- Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is
primarily for testing fsck/recovery in dry run mode, so it shouldn't
change anything besides disabling writes and holding dirty metadata
in memory.The idea here was to reduce the amount of activity if we can't write
anything out, so that bringing up a filesystem in "super ro" mode
would be more lilkely to work for data recovery - but norecovery is
the correct option for this.- btree_trans-
>locked; we now track whether a btree_trans has any btree
nodes locked, and this is used for improved assertions related to
trans_unlock() and trans_relock(). We'll also be using it for
improving how we work with lockdep in the future: we don't want
lockdep to be tracking individual btree node locks because we take
too many for lockdep to track, and it's not necessary since we have a
cycle detector.- Trigger improvements that are prep work for online fsck
- BTREE_TRIGGER_
check_repair; this regularizes how we do some repair
work for extents that goes with running triggers in fsck, and fixes
some subtle issues with transaction restarts there.- bch2_snapshot_
equiv() has now been ripped out of fsck.c; snapshot
equivalence classes are for when snapshot deletion leaves behind
redundant snapshot nodes, but snapshot deletion now cleans this up
right away, so the abstraction doesn't need to leak.- Improvements to how we resume writing to the journal in recovery. The
code for picking the new place to write when reading the journal is
greatly simplified and we also store the position in the superblock
for when we don't read the journal; this means that we preserve more
of the journal for list_journal debugging.- Improvements to sysfs btree_cache and btree_node_cache, for debugging
memory reclaim.- We now detect when we've blocked for 10 seconds on the allocator in
the write path and dump some useful info.- Safety fixes for devices references: this is a big series that
changes almost all device lookups to properly check if the device
exists and take a reference to it.Previously we assumed that if a bkey exists that references a device
then the device must exist, and this was enforced in .invalid
methods, but this was incorrect because it meant device removal
relied on accounting being correct to not leave keys pointing to
invalid devices, and that's not something we can assume.Getting the "pointer to invalid device" checks out of our .invalid()
methods fixes some long standing device removal bugs; the only
outstanding bug with device removal now is a race between the discard
path and deleting alloc info, which should be easily fixed.- The allocator now prefers not to expand the new
member_info.btree_ allocated bitmap, meaning if repair ever requires
scanning for btree nodes (because of a corrupt interior nodes) we
won't have to scan the whole device(s).- New coding style document, which among other things talks about the
correct usage of assertions* tag 'bcachefs-

/proc/allocinfo) whereabouts in the kernel memory is being
allocated: number of calls and amount of memory.- Matthew Wilcox has provided the series "Various significant MM
patches" which does a number of rather unrelated things, but in
largely similar code sites.- In his series "mm: page_alloc: freelist migratetype hygiene"

improve hugetlb allocation reliability.- Liu Shixin has hit an I/O meltdown caused by readahead in a
memory-tight memcg. Addressed in the series "Fix I/O high when
memory almost met memcg limit".- In the series "mm/filemap: optimize folio adding and splitting"

performance improvement in one test.- Baoquan He has cleaned up and consolidated the early zone
initialization code in the series "mm/mm_init.c: refactor

counters".- Some zswap cleanups from Yosry Ahmed in the series "zswap
same-filled and limit checking cleanups".- Matthew Wilcox has been looking at buffer_head code and found the
documentation to be lacking. The series is "Improve buffer head
documentation". - Multi-size THPs get more work, this time from Lance Yang. His
series "mm/madvise: enhance lazyfreeing with mTHP in madvise_free"
optimizes the freeing of these things.- Kemeng Shi has added more userspace-visible writeback
instrumentation in the series "Improve visibility of writeback". - Kemeng Shi then sent some maintenance work on top in the series
