Pull bcachefs fixes from Kent Overstreet:
"Various syzbot fixes, and the more notable ones:

- Fix for pointers in an extent overflowing the max (16) on a
filesystem with many devices: we were creating too many cached
copies when moving data around. Now, we only create at most one
cached copy if there's a promote target set.

Caching will be a bit broken for reflinked data until 6.13: I have
larger series queued up which significantly improves the plumbing
for data options down into the extent (bch_extent_rebalance) to fix
this.

- Fix for deadlock on -ENOSPC on tiny filesystems

Allocation from the partial open_bucket list wasn't correctly
accounting partial open_buckets as free: this fixes the main cause
of tests timing out in the automated tests"

Pull bcachefs fixes from Kent Overstreet:
"Lots of hotfixes:

- transaction restart injection has been shaking out a few things

- fix a data corruption in the buffered write path on -ENOSPC, found
by xfstests generic/299

- Some small show_options fixes

- Repair mismatches in inode hash type, seed: different snapshot
versions of an inode must have the same hash/type seed, used for
directory entries and xattrs. We were checking the hash seed, but
not the type, and a user contributed a filesystem where the hash
type on one inode had somehow been flipped; these fixes allow his
filesystem to repair.

Additionally, the hash type flip made some directory entries
invisible, which were then recreated by userspace; so the hash
check code now checks for duplicate non dangling dirents, and
renames one of them if necessary.

- Don't use wait_event_interruptible() in recovery: this fixes some
filesystems failing to mount with -ERESTARTSYS

- Workaround for kvmalloc not supporting > INT_MAX allocations,
causing an -ENOMEM when allocating the sorted array of journal
keys: this allows a 75 TB filesystem to mount

- Make sure bch_inode_unpacked.bi_snapshot is set in the old inode
compat path: this alllows Marcin's filesystem (in use since before
6.7) to repair and mount"

Merge tag 'bcachefs-2024-09-21' of git://evilpiepirate.org/bcachefs

Pull bcachefs updates from Kent Overstreet:

- rcu_pending, btree key cache rework: this solves lock contenting in
the key cache, eliminating the biggest source of the srcu lock hold
time warnings, and drastically improving performance on some metadata
heavy workloads - on multithreaded creates we're now 3-4x faster than
xfs.

- We're now using an rhashtable instead of the system inode hash table;
this is another significant performance improvement on multithreaded
metadata workloads, eliminating more lock contention.

- for_each_btree_key_in_subvolume_upto(): new helper for iterating over
keys within a specific subvolume, eliminating a lot of open coded
"subvolume_get_snapshot()" and also fixing another source of srcu
lock time warnings, by running each loop iteration in its own
transaction (as the existing for_each_btree_key() does).

- More work on btree_trans locking asserts; we now assert that we don't
hold btree node locks when trans->locked is false, which is important
because we don't use lockdep for tracking individual btree node
locks.

- Some cleanups and improvements in the bset.c btree node lookup code,
from Alan.

- Rework of btree node pinning, which we use in backpointers fsck. The
old hacky implementation, where the shrinker just skipped over nodes
in the pinned range, was causing OOMs; instead we now use another
shrinker with a much higher seeks number for pinned nodes.

- Rebalance now uses BCH_WRITE_ONLY_SPECIFIED_DEVS; this fixes an issue
where rebalance would sometimes fall back to allocating from the full
filesystem, which is not what we want when it's trying to move data
to a specific target.

- Use __GFP_ACCOUNT, GFP_RECLAIMABLE for btree node, key cache
allocations.

- Idmap mounts are now supported (Hongbo Li)

- Rename whiteouts are now supported (Hongbo Li)

- Erasure coding can now handle devices being marked as failed, or
forcibly removed. We still need the evacuate path for erasure coding,
but it's getting very close to ready for people to start using.
