#     Merge tag 'for-5.6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull more btrfs updates from David Sterba:
#      "Fixes that arrived after the merge window freeze, mostly stable
#       material.
#     
#        - fix race in tree-mod-log element tracking
#     
#        - fix bio flushing inside extent writepages
#     
#        - fix assertion when in-memory tracking of discarded extents finds an
#          empty tree (eg. after adding a new device)
#     
#        - update logic of temporary read-only block groups to take into
#          account overcommit
#     
#        - fix some fixup worker corner cases:
#            - page could not go through proper COW cycle and the dirty status
#              is lost due to page migration
#            - deadlock if delayed allocation is performed under page lock
#     
#        - fix send emitting invalid clones within the same file
#     
#        - fix statfs reporting 0 free space when global block reserve size is
#          larger than remaining free space but there is still space for new
#          chunks"

#     * tag 'for-5.6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
#       btrfs: do not zero f_bavail if we have available space
#       Btrfs: send, fix emission of invalid clone operations within the same file
#       btrfs: do not do delalloc reservation under page lock
#       btrfs: drop the -EBUSY case in __extent_writepage_io
#       Btrfs: keep pages dirty when using btrfs_writepage_fixup_worker
#       btrfs: take overcommit into account in inc_block_group_ro
#       btrfs: fix force usage in inc_block_group_ro
#       btrfs: Correctly handle empty trees in find_first_clear_extent_bit
#       btrfs: flush write bio if we loop in extent_write_cache_pages
#       Btrfs: fix race between adding and putting tree mod seq elements and nodes
