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/sysfs.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/btrfs/sysfs.c') diff --git a/fs/btrfs/sysfs.c b/fs/btrfs/sysfs.c index a8bafed931f4..6af7b58e1a90 100644 --- a/fs/btrfs/sysfs.c +++ b/fs/btrfs/sysfs.c @@ -923,7 +923,7 @@ out1: return ret; } -void btrfs_exit_sysfs(void) +void __cold btrfs_exit_sysfs(void) { sysfs_remove_group(&btrfs_kset->kobj, &btrfs_feature_attr_group); kset_unregister(btrfs_kset); -- cgit v1.2.3
