selftests is a pretty scrappy place.  It's partly a dumping ground for
things so useful test code doesn't just get lost and bitrotted.  Partly
a framework so people who add features can easily test them. Partly to
provide tools to architecture maintainers when they wire up new
syscalls and the like.

Yeah, ipc, for instance, also sucks _badly_ in selftests.

What testsuite should people be using for IPC?

The best I've found is using the ipc parts of LTP. It's caught a lot of
bugs in the past. Unsurprisingly, I believe Fengguang has this
automated.

Manfred also has a few for more specific purposes -- which also serve
for performance testing:

https://github.com/manfred-colorfu/ipcscale

iirc Dave Hansen also had written some shm-specific tests.
