Better to have detailed commit log.

_supported_fs generic

Other _require rules make sure we have everything we need, so no need to
restrict supported fs to xfs and ext4. (And if we really want to do so,
the test should be a "shared" test, not generic.)

Not testing per-file flag now, the name seems a bit misleading.

Assuming TEST_DIR isn't a DAX mount, which seems not always the case.

Perhaps you can check mount options of TEST_DEV using _fs_options() to
see if it's mounted with dax, and _notrun if it is.

Thanks,

v2 :
  Merge helper function changes into the first patch;
  Rewrite _require_dax, check options for sure;
  Print msg in t_mmap_dio.c to show which test going wrong;
  Empty mount options and check after mount to ensure we
wont mount with wrong option;
  Remove unnecessary leading underscore and _fail;
  Use xfs_io instead of dd;
  Other minor fixes.

Test status:
  Both cases not run on normal block device;
  Both cases PASS on ramdisk based pmem devices;
  Both cases FAIL on nvdimm devices with:
    +write(Bad address) len 1024 dax to nondax
    +write(Bad address) len 4096 dax to nondax
    +write(Bad address) len 16777216 dax to nondax
    +write(Bad address) len 67108864 dax to nondax

Xiong Zhou (2):
  xfs: test per-inode DAX flag by IO
  generic: test mmap dio through DAX and non-DAX
