[GIT PULL] Btrfs fix for 4.17-rc6

[David Sterba <dsterba@suse.com>]

Hi,

please consider pulling a fix for btrfs. This time it's really a
one-liner and 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.
Thanks.
