#     Merge tag 'for-5.16-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull btrfs updates from David Sterba:
#      "The updates this time are more under the hood and enhancing existing
#       features (subpage with compression and zoned namespaces).
#     
#       Performance related:
#     
#        - misc small inode logging improvements (+3% throughput, -11% latency
#          on sample dbench workload)
#     
#        - more efficient directory logging: bulk item insertion, less tree
#          searches and locking
#     
#        - speed up bulk insertion of items into a b-tree, which is used when
#          logging directories, when running delayed items for directories
#          (fsync and transaction commits) and when running the slow path
#          (full sync) of an fsync (bulk creation run time -4%, deletion -12%)
#     
#       Core:
#     
#        - continued subpage support
#           - make defragmentation work
#           - make compression write work
#     
#        - zoned mode
#           - support ZNS (zoned namespaces), zone capacity is number of
#             usable blocks in each zone
#           - add dedicated block group (zoned) for relocation, to prevent
#             out of order writes in some cases
#           - greedy block group reclaim, pick the ones with least usable
#             space first
#     
#        - preparatory work for send protocol updates
#     
#        - error handling improvements
#     
#        - cleanups and refactoring
#     
#       Fixes:
#     
#        - lockdep warnings
#           - in show_devname callback, on seeding device
#           - device delete on loop device due to conversions to workqueues
#     
#        - fix deadlock between chunk allocation and chunk btree modifications
#     
#        - fix tracking of missing device count and status"
