#
# Verify the inheritance behavior of FS_XFLAG_DAX flag in various combinations.
# 1) New files and directories automatically inherit FS_XFLAG_DAX from their parent directory.
# 2) cp operation make files and directories inherit the FS_XFLAG_DAX from new parent directory.
# 3) mv operation make files and directories preserve the FS_XFLAG_DAX from old parent directory.
# In addition, setting/clearing FS_XFLAG_DAX flag is not impacted by dax mount options.
