From 4bceb18f1551c8c047eeb54d48cda9f5453dc12f Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Tue, 29 Oct 2013 22:11:51 +1100 Subject: [PATCH] xfs: vectorise DA btree operations The remaining non-vectorised code for the directory structure is the node format blocks. This is shared with the attribute tree, and so is slightly more complex to vectorise. Introduce a "non-directory" directory ops structure that is attached to all non-directory inodes so that attribute operations can be vectorised for all inodes. Once we do this, we can vectorise all the da btree operations. Because this patch adds more infrastructure than it removes the binary size does not decrease: text data bss dec hex filename 794490 96802 1096 892388 d9de4 fs/xfs/xfs.o.orig 792986 96802 1096 890884 d9804 fs/xfs/xfs.o.p1 792350 96802 1096 890248 d9588 fs/xfs/xfs.o.p2 789293 96802 1096 887191 d8997 fs/xfs/xfs.o.p3 789005 96802 1096 886903 d8997 fs/xfs/xfs.o.p4 789061 96802 1096 886959 d88af fs/xfs/xfs.o.p5 789733 96802 1096 887631 d8b4f fs/xfs/xfs.o.p6 Signed-off-by: Dave Chinner Reviewed-by: Ben Myers Signed-off-by: Ben Myers --- fs/xfs/xfs_attr_inactive.c | 3 +- fs/xfs/xfs_attr_leaf.c | 3 +- fs/xfs/xfs_attr_list.c | 11 ++-- fs/xfs/xfs_da_btree.c | 104 ++++++++++++++++++++----------------- fs/xfs/xfs_da_format.c | 59 +++++++++++++++++++++ fs/xfs/xfs_da_format.h | 25 --------- fs/xfs/xfs_dir2.c | 7 ++- fs/xfs/xfs_dir2.h | 6 +++ fs/xfs/xfs_iops.c | 1 + fs/xfs/xfs_mount.h | 1 + 10 files changed, 139 insertions(+), 81 deletions(-) diff --git a/fs/xfs/xfs_attr_inactive.c b/fs/xfs/xfs_attr_inactive.c index f33fb62b7f17..4855085f8c6b 100644 --- a/fs/xfs/xfs_attr_inactive.c +++ b/fs/xfs/xfs_attr_inactive.c @@ -40,6 +40,7 @@ #include "xfs_quota.h" #include "xfs_trace.h" #include "xfs_dinode.h" +#include "xfs_dir2.h" /* * Look at all the extents for this logical region, @@ -236,7 +237,7 @@ xfs_attr3_node_inactive( xfs_trans_brelse(*trans, bp);
