From fc1829f34d30899701dfd5890030d39e13e1f47d Mon Sep 17 00:00:00 2001 From: David Chinner Date: Thu, 30 Oct 2008 17:39:46 +1100 Subject: [XFS] Add ail pointer into log items Add an xfs_ail pointer to log items so that the log items can reference the AIL directly during callbacks without needed a struct xfs_mount.
