[LTP] [PATCH] [RFC] syscalls/ipc: Rename some msgctl tests

[Cyril Hrubis]

The test from msgctl08 to msgctl11 are actually msg stress tests, these
do not actually call msgctl() during the test but rather than that they
fork large number of processes and send message around. Renaming them to
msgstress seems to be more fitting.

Agreed. These tests fork too many times, and they often trigger OOM at
runtime. So I think this patch make sense.
​
Another thought of mine is that to remove them from the ltplite and
syscalls runtest file. what about just putting them in stress.part3?

These shouldn't be part of ltplite for sure, I will remove them in a
follow up patch. I would like to keep them in the syscalls runtest file
though and make sure that they scale better accordingly to system
RAM/CPUs later on.

Great. It sounds good to adjust their fork numbers according to the system
config.
