Stefan Hajnoczi 31be8a2a97 block/file-posix: add x-check-page-cache=on|off option ...

mincore(2) checks whether pages are resident.  Use it to verify that
page cache has been dropped.

You can trigger a verification failure by mmapping the image file from
another process that loads a byte from a page, forcing it to become
resident.  bdrv_co_invalidate_cache() will fail while that process is
alive.
