From 288699fecaffa1ef8f75f92020cbb593a772e487 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 23 Jun 2010 18:11:15 +1000 Subject: xfs: drop dmapi hooks Dmapi support was never merged upstream, but we still have a lot of hooks bloating XFS for it, all over the fast pathes of the filesystem. This patch drops over 700 lines of dmapi overhead. If we'll ever get HSM support in mainline at least the namespace events can be done much saner in the VFS instead of the individual filesystem, so it's not like this is much help for future work.
