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.

This patches instead makes xfs_trans_ijoin usable on it's own by doing an implicity xfs_trans_ihold, which also allows us to drop the third argument. For the case where we want to hold a reference on the inode a xfs_trans_ijoin_ref wrapper is added which does the IHOLD and marks the inode for needing an xfs_iput. In addition to the cleaner interface to the caller this also simplifies the implementation.

For most simple callers we now use the simple inode class, which used to be the iget class, but add more details tracing for namespace events, which now includes the name of the directory entries manipulated. Remove the xfs_inactive trace point, which is a duplicate of the clear_inode one, and the xfs_change_file_space trace point, which is immediately followed by the more specific alloc/free space trace points.
