#     Merge tag 'for-4.17-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
#     
#     Pull btrfs fix from David Sterba:
#      "A one-liner that prevents leaking an internal error value 1 out of the
#       ftruncate syscall.
#     
#       This has been observed in practice. The steps to reproduce make a
#       common pattern (open/write/fync/ftruncate) but also need the
#       application to not check only for negative values and happens only for
#       compressed inlined files.
#     
#       The conditions are narrow but as this could break userspace I think
#       it's better to merge it now and not wait for the merge window"
