Subject: [RFC 3/5] xfs: allow fs freeze on suspend/hibernation
Date: Tue, 3 Oct 2017 11:53:11 -0700 [thread overview]
Message-ID: <20171003185313.1017-4-mcgrof@kernel.org> (raw)
In-Reply-To: <20171003185313.1017-1-mcgrof@kernel.org>
This also removes the freezer calls on the XFS kthread as they are
no longer needed.
Signed-off-by: Luis R. Rodriguez <mcgrof@kernel.org>
