Assuming you have some test-cases that you've run them through, then yes:

 Signed-off-by: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>

for both. But since I can't really test them myself, I'd really like
that. I did these patches just by looking at the source code, and
while I think that's an excellent way to do development, I do think
that testing is _also_ required.

And that second patch was obviously not even build-tested, so really
just a "something like this".

Sounds good.

Your suggested version with just "list_add()" and a comment about why
it doesn't need RCU safety looks good. And the build fix obviously
requited ;)
