I would rephrase the short to simply say Remove unused variable, as refactor implies more extensive changes than what this patch is actually doing.

In the realm of linux security modules ctx is short for "context". I used tctx here because I was lazy. It would be much better to drop tctx, even if it means a tiny bit more change.

Amit has already posted a v2 with the requested changes, but I wanted to get back to you on this even if this patch is outdated ... Shuah, what is your preference for things like this? My general policy is that patches only affecting one subsystem tree should be taken by the associated subsystem to minimize merge headaches and other ugliness, however, the kselftest is an interesting subsystem in that it relies so heavily on others that I'm not sure my policy makes as much sense here :)

kselftest patches usually go through subsystem trees because of the merge problems you mentioned. I take them through kselftest tree if subsystem maintainers want me to. Some do and I pick them up.
I pick up patches if I don't see response from subsystem maintainers.
