From 9e4871070b5f070cacf26525389d56e0345ba156 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Mon, 1 Aug 2011 12:08:18 -0400 Subject: [PATCH] Btrfs: skip looking for delalloc if we don't have ->fill_delalloc We always look for delalloc bytes in our io_tree so we can fill in delalloc. This is fine in most cases, but if we're writing out the btree_inode this is just a superfluous tree search on the io_tree, and if we have a lot of metadata dirty this could be an expensive check. So instead check to see if our io_tree has a ->fill_delalloc op, and if not don't even bother doing the lookup. Thanks, Signed-off-by: Josef Bacik --- Reading git-format-patch failed
