Subject: xfs_io: allow resvsp command for foreign filesystems
X-Git-Tag: v3.1.3~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=370f69dd8d280ceeca77b00d5d44ac9bfe58315b;p=thirdparty%2Fxfsprogs-dev.git

xfs_io: allow resvsp command for foreign filesystems

Recent kernels implement the RESVP ioctl in common code, so using
command for non-XFS filesystems is fine.
