[v8,0/7] Make fstests support new behavior of DAX

Message

Xiao Yang Aug. 3, 2020, 8:38 a.m. UTC

The new behavior of DAX on xfs/ext4 has been merged into main kernel
so it is time for fstests to support new behavior of DAX.

1) Refactor common functions and take use of them.
2) Move and update xfs/260.
3) Add two new tests to verify some features.

V7->V8:
1) Rebase against the latest xfstests.
2) Factor out _check_s_dax() and _check_xflag().

Xiao Yang (7):
  common/rc: Introduce helpers for new dax mount options and
    FS_XFLAG_DAX
  fstests: Use _require_scratch_dax_mountopt() and _require_dax_iflag()
  generic/223: Don't clear MKFS_OPTION before calling
    _scratch_mkfs_geom()
  generic/413, xfs/260: Improve format operation for PMD fault testing
  xfs/260: Move and update xfs/260
  generic: Verify if statx() can qurey S_DAX flag on regular file
    correctly
  generic: Verify the inheritance behavior of FS_XFLAG_DAX flag in
    various combinations
