Subject: [PATCH 4.14 12/52] xfs: convert XFS_AGFL_SIZE to a helper function
Date: Mon, 4 Jun 2018 08:58:07 +0200 [thread overview]
Message-ID: <20180604065607.026729570@linuxfoundation.org> (raw)
In-Reply-To: <20180604065606.532044490@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dave Chinner <dchinner@redhat.com>
commit a78ee256c325ecfaec13cafc41b315bd4e1dd518 upstream.
The AGFL size calculation is about to get more complex, so lets turn
the macro into a function first and remove the macro.
