From a9c21c1b9deaced836034e77fe25fe0b55c21f02 Mon Sep 17 00:00:00 2001 From: David Chinner Date: Thu, 30 Oct 2008 17:39:35 +1100 Subject: [XFS] Given the log a pointer to the AIL When we need to go from the log to the AIL, we have to go via the xfs_mount. Add a xfs_ail pointer to the log so we can go directly to the AIL associated with the log.
