From 2fa389c5eb8c97d621653184d2adf5fdbd4a3167 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 23 Jun 2005 00:09:16 -0700 Subject: [PATCH] quota: sanitize dentry handling in vfs_quota_on_mount Use lookup_one_len instead of opencoding a simplified lookup using lookup_hash with a fake hash. Also there's no need anymore for the d_invalidate as we have a completely valid dentry now.
