From 1b1dcc1b57a49136f118a0f16367256ff9994a69 Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Mon, 9 Jan 2006 15:59:24 -0800 Subject: [PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_sem This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different.
