From 794ee1baee1c26be40410233e6c20bceb2b03c08 Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Mon, 9 Jan 2006 15:59:21 -0800 Subject: [PATCH] mutex subsystem, semaphore to mutex: XFS This patch switches XFS over to use the new mutex code directly as opposed to the previous workaround patch I posted earlier that avoided the namespace clash by forcing it back to semaphores. This falls in the 'works for me' category.
