X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5e28aafe708ba3e388f92a7148093319d3521c2f;p=linux.git

xfs: simplify a check in xfs_ioctl_setattr_check_cowextsize

Only v5 file systems can have the reflink feature, and those will
always use the large dinode format.  Remove the extra check for the
inode version.
