From aac72277fda6ef788bb8d5deaa502ce9b9b6e472 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 26 Jan 2011 20:06:06 +0000 Subject: rwsem: Move duplicate function prototypes to linux/rwsem.h All architecture specific rwsem headers carry the same function prototypes. Just x86 adds asmregparm, which is an empty define on all other architectures. S390 has a stale rwsem_downgrade_write() prototype. Remove the duplicates and add the prototypes to linux/rwsem.h Signed-off-by: Thomas Gleixner Cc: Peter Zijlstra Cc: David Howells Cc: Benjamin Herrenschmidt Cc: Richard Henderson Acked-by: Tony Luck Acked-by: Heiko Carstens Cc: Paul Mundt Acked-by: David Miller Cc: Chris Zankel LKML-Reference: <20110126195833.970840140@linutronix.de> Signed-off-by: Thomas Gleixner --- arch/ia64/include/asm/rwsem.h | 5 ----- 1 file changed, 5 deletions(-) (limited to 'arch/ia64/include/asm/rwsem.h') diff --git a/arch/ia64/include/asm/rwsem.h b/arch/ia64/include/asm/rwsem.h index 148b61a96b8..3027e7516d8 100644 --- a/arch/ia64/include/asm/rwsem.h +++ b/arch/ia64/include/asm/rwsem.h @@ -34,11 +34,6 @@ #define RWSEM_ACTIVE_READ_BIAS RWSEM_ACTIVE_BIAS #define RWSEM_ACTIVE_WRITE_BIAS (RWSEM_WAITING_BIAS + RWSEM_ACTIVE_BIAS) -extern struct rw_semaphore *rwsem_down_read_failed(struct rw_semaphore *sem); -extern struct rw_semaphore *rwsem_down_write_failed(struct rw_semaphore *sem); -extern struct rw_semaphore *rwsem_wake(struct rw_semaphore *sem); -extern struct rw_semaphore *rwsem_downgrade_wake(struct rw_semaphore *sem); - /* * lock for reading */ -- cgit v1.2.3
