[PATCH] v9fs: assign dentry ops to negative dentries

[Eric Van Hensbergen <ericvh@hera.kernel.org>]

Subject: [PATCH] assign dentry ops to negative dentries
From: Latchesar Ionkov <lucho@ionkov.net>
Date: 1142219619 -0500

If a file is not found in v9fs_vfs_lookup, the function creates negative
dentry, but doesn't assign any dentry ops. This leaves the negative entry
in the cache (there is no d_delete to mark it for removal). If the file is
created outside of the mounted v9fs filesystem, the file shows up in the
directory with weird permissions.

This patch assigns the default v9fs dentry ops to the negative dentry.
