Trond Myklebust 6d09bb627d [PATCH] fs/namei.c: Call to file_permission() under a spinlock in do_lookup_path() ... 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.
