I wonder if rename is a good thing to do, because it complicates git history.
I'd keep old names.
Also in the past we didn't rename, e.g. in 1c44244849 ("getuid, getgid, setuid,
setgid: fixed 16-bit versions")
testcases/kernel/syscalls/getuid/getuid02.c was renamed to
testcases/kernel/syscalls/geteuid/geteuid02.c to match the new test coverage,
but testcases/kernel/syscalls/getuid/getuid03.c stayed the same (not renamed to
testcases/kernel/syscalls/getuid/getuid02.c, which was then free).

Or maybe better example: testcases/kernel/syscalls/kill/kill01.c got deleted
in eafdc5dd83 ("syscalls/kill01: Remove it"), but test names did not shift.

Kind regards,
Petr
