madvice: new case for madvise(WILLNEED) Page fault occurs in spite that madvise(WILLNEED) system call is called to prefetch the page. This issue is reproduced by running a program which sequentially accesses to a shared memory and calls madvise(WILLNEED) to the next page on a page fault. Fixed by commit: 55231e5c898 mm: madvise: fix MADV_WILLNEED on shmem swapouts Signed-off-by: Li Wang <liwang@redhat.com>
