1) With new kernel(e.g. v5.8-rc1), statx() can be used to qurey S_DAX flag on regular file, so add a test to verify the feature. 2) Factor out _check_s_dax() so that other tests can use it in future.

# 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
