#     Merge tag 'bcachefs-2024-04-15' of https://evilpiepirate.org/git/bcachefs
#     
#     Pull yet more bcachefs fixes from Kent Overstreet:
#      "This gets recovery working again for the affected user I've been
#       working with, and I'm still waiting to hear back on other bug reports
#       but should fix it for everyone else who's been having issues with
#       recovery.
#     
#        - Various recovery fixes:
#     
#            - fixes for the btree_insert_entry being resized on path
#              allocation btree_path array recently became dynamically
#              resizable, and btree_insert_entry along with it; this was being
#              observed during journal replay, when write buffer btree updates
#              don't use the write buffer and instead use the normal btree
#              update path
#     
#            - multiple fixes for deadlock in recovery when we need to do lots
#              of btree node merges; excessive merges were clocking up the
#              whole pipeline
#     
#            - write buffer path now correctly does btree node merges when
#              needed
#     
#            - fix failure to go RW when superblock indicates recovery passes
#              needed (i.e. to complete an unfinished upgrade)
#     
#        - Various unsafety fixes - test case contributed by a user who had
#          two drives out of a six drive array write out a whole bunch of
#          garbage after power failure
#     
#        - New (tiny) on disk format feature: since it appears the btree node
#          scan tool will be a more regular thing (crappy hardware, user
#          error) - this adds a 64 bit per-device bitmap of regions that have
#          ever had btree nodes.
#     
#        - A path->should_be_locked fix, from a larger patch series tightening
#          up invariants and assertions around btree transaction and path
#          locking state.
#     
#          This particular fix prevents us from keeping around btree_paths
#          that are no longer needed"
