This one was due to a merge error: we added a use of nd.path in commit2d7c820e56
("ext3: add checks for errors from jbd"), and concurrently we got rid of 'nd' and used a naked 'path' in commit8264613def
("[PATCH] switch quota_on-related stuff to kern_path()"). That all merged cleanly, but it didn't actually _work_. This should fix it. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
