[PATCH v2 0/2] prevent mincore() page cache leaks

Here's a new version of the mincore() patches, with feedback from Andrew Morton
applied. The IOCB_NOWAIT patch was dropped since David Chinner pointed out it's
incomplete. We definitely want the first patch, while for the second Linus
said:

  I think that's fine, and probably the right thing to do, but I also
  suspect that nobody actually cares ;(

Whether or not somebody cares, we should hear of no breakage. If somebody does
care after all, without second patch we might hear of breakage, so I would
suggest applying it. It's not that complicated after all (famous last words?)
