#include <linux/semaphore.h>-
由 Matthew Wilcox 提交于
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. Signed-off-by: NMatthew Wilcox <willy@linux.intel.com> Acked-by: NIngo Molnar <mingo@elte.hu>
