[PATCH 5.4 V2] xfs: simplify a check in xfs_ioctl_setattr_check_cowextsize

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Christoph Hellwig <hch@xxxxxx>

commit 5e28aafe708ba3e388f92a7148093319d3521c2f upstream.

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.
