From 4eb984d3ab5641ce7992204756ac15a61f5f7181 Mon Sep 17 00:00:00 2001 From: Torvald Riegel Date: Tue, 23 Jun 2015 15:22:25 +0200 Subject: Clean up BUSY_WAIT_NOP and atomic_delay. This patch combines BUSY_WAIT_NOP and atomic_delay into a new atomic_spin_nop function and adjusts all clients. The new function is put into atomic.h because what is best done in a spin loop is architecture-specific, and atomics must be used for spinning. The function name is meant to tell users that this has no effect on synchronization semantics but is a performance aid for spinning. --- nscd/nscd-client.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'nscd') diff --git a/nscd/nscd-client.h b/nscd/nscd-client.h index 43a8c61..740e2f9 100644 --- a/nscd/nscd-client.h +++ b/nscd/nscd-client.h @@ -378,7 +378,7 @@ __nscd_acquire_maplock (volatile struct locked_map_ptr *mapptr) if (__glibc_unlikely (++cnt > 5)) return false; - atomic_delay (); + atomic_spin_nop (); } return true; -- cgit v1.1
