tomoyo: reduce mmap_sem hold for mm->exe_file
The mm->exe_file is currently serialized with mmap_sem (shared) in order to both safely (1) read the file and (2) compute the realpath by calling tomoyo_realpath_from_path, making it an absolute overkill. Good users will, on the other hand, make use of the more standard get_mm_exe_file(), requiring only holding the mmap_sem to read the value, and relying on reference [ coding-style fixes] Signed-off-by: Davidlohr Bueso <> Acked-by: Tetsuo Handa <> Cc: James Morris <> Signed-off-by: Andrew Morton <> Signed-off-by: Linus Torvalds <>
