Hi!

quoted

As it is it's pretty clear where the environment variable comes from, if
we rename it to TST_IPC_PATH it's not obvious that this has been
exported by LTP test.

I was thinking about it as well (just forget to write that into cover letter).

Generally things that are visible on the running system tends to be
prefixed with LTP_ or ltp_ rather than TST_ or tst_...

Sure. I just thought that LTP_ is for variables which are expected to be set by
user. But let's keep the old name. How about the first commit (cleanup)?

There is no such rule I guess.

It has been case by case, for instance we do have KCONFIG_PATH which we
agreed on with the testing community to be a canonical variable name
that is shared between different frameworks.
