Subject: Re: [PATCH v2 2/3] mm: Update file times when inodes are written
 after mmaped writes

NAK, we went through great trouble to get rid of the nasty layering
violation where the VM called file_update_time directly just a short
while ago, reintroducing that is a massive step back.

Make sure whatever "solution" for your problem you come up with keeps
the file update in the filesystem or generic helpers.
