[LTP] [PATCH v5 5/6] lib: Merge functionality of LTP_QUIET into LTP_REPRODUCIBLE_OUTPUT

[Petr Vorel]

Hi Martin,

any change I'd get your explicit ack to this change
(your Acked-by: or Reviewed-by: ?). It should be safe for Valgrind, but better
you to double check.

> LTP_REPRODUCIBLE_OUTPUT=1 environment variable was added in 5894abc5f to
> help valgrind to use LTP for testing. It discards the actual content of
> the messages printed by the test (removes everything after printing
> TINFO/TPASS/TFAIL/... flag).

> Later LTP_QUIET=1 was added which suppresses printing TCONF, TINFO, and
> TDEBUG messages.

> Valgrind project uses both variables but no need to handle them
> separately. Therefore merge functionality of LTP_QUIET into
> LTP_REPRODUCIBLE_OUTPUT.

> LTP_QUIET was not even documented in HTML doc.

> Also fix help description, because TWARN was not skipped, although doc
> claimed to do.

> Implements: https://github.com/linux-test-project/ltp/issues/1306

> Changes v4->v5:
> * Remove wrongly stated TWARN (error on code on master)
> * Fix missing new lines in help (AI)
> * Use single fprintf (Li)

Also AI found missing 's': s/uppress/suppress/
I'll fix that before merging.

Kind regards,
