Usually yes, but I believe LOCALVERSION can be appended to
KERNELRELEASE / UTS_RELEASE which can makes it much longer.

That's correct, it was not matching even when it was introduced.  I am
simply taking that as people caring about the content and not simply
making rxrpc_version_string == UTS_RELEASE.  The current format is:

"linux-" UTS_RELEASE " AF_RXRPC"
