# By the following cases, verify if statx() can query S_DAX flag
# on regular file correctly.
# 1) With dax=always option, FS_XFLAG_DAX is ignored and S_DAX flag
# always exists on regular file.
# 2) With dax=inode option, setting/clearing FS_XFLAG_DAX can change
# S_DAX flag on regular file.
# 3) With dax=never option, FS_XFLAG_DAX is ignored and S_DAX flag
# never exists on regular file.
