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/file.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/btrfs/file.c') diff --git a/fs/btrfs/file.c b/fs/btrfs/file.c index 41ab9073d1d4..a335e2e6c84d 100644 --- a/fs/btrfs/file.c +++ b/fs/btrfs/file.c @@ -3378,7 +3378,7 @@ const struct file_operations btrfs_file_operations = { .dedupe_file_range = btrfs_dedupe_file_range, }; -void btrfs_auto_defrag_exit(void) +void __cold btrfs_auto_defrag_exit(void) { kmem_cache_destroy(btrfs_inode_defrag_cachep); } -- cgit v1.2.3
