From 1de87444f8f91009b726108c9a56600645ee8751 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Tue, 24 Jan 2006 15:22:50 -0600 Subject: JFS: semaphore to mutex conversion. the conversion was generated via scripts, and the result was validated automatically via a script as well. build and boot tested.
