The various semaphore functions all directly translate into sema_init(), down() and up(), so we can just remove the API. This is a mostly automated conversion using simple sed scripts, plus some manual changes to account for down() returning no error. As a positive side-effect, down() no longer hangs after receiving a signal, as the original code did by looping around down_interruptible. The semaphores still need to be turned into mutexes as a follow-up step. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
