From e67c718b5b9a306bde7e966be7b4ca48fa063d73 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Mon, 19 Feb 2018 17:24:18 +0100 Subject: btrfs: add more __cold annotations The __cold functions are placed to a special section, as they're expected to be called rarely. This could help i-cache prefetches or help compiler to decide which branches are more/less likely to be taken without any other annotations needed. Though we can't add more __exit annotations, it's still possible to add __cold (that's also added with __exit). That way the following function categories are tagged: - printf wrappers, error messages - exit helpers Signed-off-by: David Sterba --- fs/btrfs/inode.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/btrfs/inode.c') diff --git a/fs/btrfs/inode.c b/fs/btrfs/inode.c index 491a7397f6fa..bb5de52cbc09 100644 --- a/fs/btrfs/inode.c +++ b/fs/btrfs/inode.c @@ -9478,7 +9478,7 @@ static void init_once(void *foo) inode_init_once(&ei->vfs_inode); } -void btrfs_destroy_cachep(void) +void __cold btrfs_destroy_cachep(void) { /* * Make sure all delayed rcu free inodes are flushed before we -- cgit v1.2.3
