Subject: [PATCH] xfs: fix xfs_reflink_unshare usage of filemap_write_and_wait_range
Date: Wed, 28 Apr 2021 22:44:16 -0700	[thread overview]
Message-ID: <20210429054416.GJ1251862@magnolia> (raw)

From: Darrick J. Wong <djwong@kernel.org>

The final parameter of filemap_write_and_wait_range is the end of the
range to flush, not the length of the range to flush.

Fixes: 46afb0628b86 ("xfs: only flush the unshared range in xfs_reflink_unshare")
