Revision 6d09bb627d2470299dfb1af0e6d27fb4aece9196 authored by Trond Myklebust on 04 June 2006, 09:51:37 UTC, committed by Linus Torvalds on 05 June 2006, 19:29:16 UTC
From: Trond Myklebust <Trond.Myklebust@netapp.com> We're presently running lock_kernel() under fs_lock via nfs's ->permission handler. That's a ranking bug and sometimes a sleep-in-spinlock bug. This problem was introduced in the openat() patchset. We should not need to hold the current->fs->lock for a codepath that doesn't use current->fs.
