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"
