Subject: [PATCH 5.10 CANDIDATE v2 7/7] xfs: fix xfs_reflink_unshare usage of filemap_write_and_wait_range
Date: Mon, 27 Jun 2022 10:33:11 +0300	[thread overview]
Message-ID: <20220627073311.2800330-8-amir73il@gmail.com> (raw)
In-Reply-To: <20220627073311.2800330-1-amir73il@gmail.com>

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

commit d4f74e162d238ce00a640af5f0611c3f51dad70e upstream.

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")
