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/tree-checker.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'fs/btrfs/tree-checker.c') diff --git a/fs/btrfs/tree-checker.c b/fs/btrfs/tree-checker.c index e96cfd93ae3f..8871286c1a91 100644 --- a/fs/btrfs/tree-checker.c +++ b/fs/btrfs/tree-checker.c @@ -52,6 +52,7 @@ * Allows callers to customize the output. */ __printf(4, 5) +__cold static void generic_err(const struct btrfs_fs_info *fs_info, const struct extent_buffer *eb, int slot, const char *fmt, ...) @@ -76,6 +77,7 @@ static void generic_err(const struct btrfs_fs_info *fs_info, * offset has its own meaning. */ __printf(4, 5) +__cold static void file_extent_err(const struct btrfs_fs_info *fs_info, const struct extent_buffer *eb, int slot, const char *fmt, ...) @@ -229,6 +231,7 @@ static int check_csum_item(struct btrfs_fs_info *fs_info, * which represents inode number */ __printf(4, 5) +__cold static void dir_item_err(const struct btrfs_fs_info *fs_info, const struct extent_buffer *eb, int slot, const char *fmt, ...) -- cgit v1.2.3
