From 82fa9012458d867936d7bf130e6e14bdebc6873c Mon Sep 17 00:00:00 2001 From: David Chinner Date: Thu, 30 Oct 2008 17:38:26 +1100 Subject: [XFS] Allocate the struct xfs_ail Rather than embedding the struct xfs_ail in the struct xfs_mount, allocate it during AIL initialisation. Add a back pointer to the struct xfs_ail so that we can pass around the xfs_ail and still be able to access the xfs_mount if need be. This is th first step involved in isolating the AIL implementation from the surrounding filesystem code.
