stable docs.kernel.org links?

[Bjorn Helgaas]

When providing a URL to a bit of code, it's nice if the URL remains
useful indefinitely, e.g., this should work "forever" because it
includes a git tag:

  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/pci.c?id=v6.8#n1300

Is there a similar "id=" mechanism for https://docs.kernel.org?  I
could use https://docs.kernel.org/core-api/genalloc.html, but the link
may become stale as docs get reorganized.

I could link to the .rst file directly with the git tag, e.g.,

  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/core-api/genalloc.rst?id=v6.8

but of course that's not as nicely formatted.
