#     Merge tag 'for-5.0-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull btrfs fixes from David Sterba:
#     
#      - two regression fixes in clone/dedupe ioctls, the generic check
#        callback needs to lock extents properly and wait for io to avoid
#        problems with writeback and relocation
#     
#      - fix deadlock when using free space tree due to block group creation
#     
#      - a recently added check refuses a valid fileystem with seeding device,
#        make that work again with a quickfix, proper solution needs more
#        intrusive changes
#     
#     * tag 'for-5.0-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
#       btrfs: Use real device structure to verify dev extent
#       Btrfs: fix deadlock when using free space tree due to block group creation
#       Btrfs: fix race between reflink/dedupe and relocation
#       Btrfs: fix race between cloning range ending at eof and writeback
