[v5,0/8] Make fstests support new behavior of DAX

Message

Xiao Yang July 9, 2020, 9:49 a.m. UTC

The new behavior of DAX on xfs/ext4 has been merged into main kernel
tree/ext4-dax branch 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.

Xiao Yang (8):
  common/rc: Introduce new helpers for DAX mount options and
    FS_XFLAG_DAX
  fstests: Use _require_scratch_dax_mountopt() and _require_dax_iflag()
  common/rc: Remove unused _require_scratch_dax()
  generic/223: Don't clear all mkfs options for _scratch_mkfs_geom()
    roughly
  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
