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 [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Davidlohr Bueso <dbueso@suse.de> Acked-by: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Cc: James Morris <jmorris@namei.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
