This patchset is to verify whether memory failure mechanism still works with the fsdax-rmap feature. With this feature, fsdax and reflink can be used together[1]. So, we also test it for reflinked files in filesystem mounted with dax option. Memo: (quoted from v2[2]): > Never mind. I'd like to merge these tests after your kernel patchset about > "Add reflink&dedupe support for fsdax" be merged at first. To avoid you > might add/change something. And I need to see the test works on offical > kernel at least, before merging it.

Fixed typo in .out files Changes since v1: 1. Fixed typo 2. Use `sysconf(_SC_PAGESIZE)` as page size, instead of the fixed 4KiB 3. Use `$(get_page_size)` in testcase 4.
