This will work, but you don't really need the label.  Just say
"Documentation/locking/seqlock.rst" at the other end and the
cross-reference link will happen by itself - and plain-text readers will
know where to go as well.

I did
	 :ref:`Documentation/locking/seqlock.rst <kernel_hacking_seqlock>`

and you are saying just the file path without fancy :ref: is enough.
Okay. Then I keep just SPDX tag for v2.
