| H A D | file-posix.c | 31be8a2a Fri Apr 27 16:23:12 GMT 2018 Stefan Hajnoczi <stefanha@redhat.com> 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.
