[PATCH] ufs: easy debug
Currently to turn on debug mode "user" has to edit ~10 files, to turn off he has to do it again. This patch introduce such changes: 1)turn on(off) debug messages via ".config" 2)remove unnecessary duplication of code 3)make "UFSD" macros more similar to function 4)fix some compiler warnings Signed-off-by: Evgeniy Dushistov <dushistov@mail.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
