btrfs: make set_extent_bit helpers static inline
The funcions just wrap the set_extent_bit API and generate function calls. This increases stack consumption and may negatively affect performance due to icache misses. We can simply make the helpers static inline and keep the type checking and API untouched. The code slightly increases: text data bss dec hex filename 938427 43670 23144 1005241 f56b9 fs/btrfs/btrfs.ko.before 938667 43670 23144 1005481 f57a9 fs/btrfs/btrfs.ko Signed-off-by: David Sterba <dsterba@suse.com>
