Merge tag 'bcachefs-2024-11-13' of git://evilpiepirate.org/bcachefs

Pull bcachefs fixes from Kent Overstreet:
 "This fixes one minor regression from the btree cache fixes (in the
  scan_for_btree_nodes repair path) - and the shutdown path fix is the
  big one here, in terms of bugs closed:

   - Assorted tiny syzbot fixes

   - Shutdown path fix: "bch2_btree_write_buffer_flush_going_ro()"

     The shutdown path wasn't flushing the btree write buffer, leading
     to shutting down while we still had operations in flight. This
     fixes a whole slew of syzbot bugs, and undoubtedly other strange
     heisenbugs.
