Merge tag 'bcachefs-2025-02-12' of git://evilpiepirate.org/bcachefs

Pull bcachefs fixes from Kent Overstreet:
 "Just small stuff.

  As a general announcement, on disk format is now frozen in my master
  branch - future on disk format changes will be optional, not required.

   - More fixes for going read-only: the previous fix was insufficient,
     but with more work on ordering journal reclaim flushing (and a
     btree node accounting fix so we don't split until we have to) the
     tiering_replication test now consistently goes read-only in less
     than a second.

   - fix for fsck when we have reflink pointers to missing indirect
     extents

   - some transaction restart handling fixes from Alan; the "Pass
     _orig_restart_count to trans_was_restarted" likely fixes some rare
     undefined behaviour heisenbugs"
