From a96e84293fff050414eee9a9777d358ed101dfbe Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 27 Aug 2013 13:45:57 -0700 Subject: [PATCH] backports: add generic semaphore.h Matthew generalized the semaphore implementation and part of that collateral evolution consisted of changing the header used for the expected routines from asm/semaphore.h to linux/semaphore.h. mcgrof@garbanzo ~/linux-next (git::master)$ git describe --contains \ 64ac24e738823161693bf791f87adc802cf529ff v2.6.26-rc1~1155^2~5 commit 64ac24e738823161693bf791f87adc802cf529ff Author: Matthew Wilcox Date: Fri Mar 7 21:55:58 2008 -0500 Generic semaphore implementation Semaphores are no longer performance-critical, so a generic C implementation is better for maintainability, debuggability and extensibility. Thanks to Peter Zijlstra for fixing the lockdep warning. Thanks to Harvey Harrison for pointing out that the unlikely() was unnecessary.
