[LTP] [PATCH v2 0/4] Add TDBUG tst_res() flag

[LTP] [PATCH v2 0/4] Add TDBUG tst_res() flag

[Petr Vorel]

Hi all,

this started as reduce of verbose logs in
testcases/kernel/fs/fsx-linux/fsx-linux.c. I was asked to add support
for debug flags.

TODO: shell API (nfs_lib.sh uses -v for NFS version, it needs to be
renamed.

Changes v1->v2:
* all changed - v1 simply removed few logs from fsx-linux.

Kind regards,
Petr

[LTP] [PATCH v2 2/4] lib: Add support for TDBUG tst_res() flag

[Petr Vorel]

To print more verbose info. By default it's off, printing enabled with
-v option.

Use unused value 8 (former TRETR).
Assigned color is white.

[LTP] [PATCH v2 3/4] fsx-linux: Reduce log output with TDBUG

[Petr Vorel]

Log output is very verbose thus silent with changing most verbose
TINFO messages to TDBUG. Given how many times the test tries it's a
significant time spent for printing output. This change also helps to
run on slower SUT without need to set LTP_TIMEOUT_MUL environment
variable.

My first impression was it's some kind of new BUG type :-)
I'd suggest making it TDEBUG or TDBG.

Agree it looks strange. We wanted to keep 5 letters.
Therefore maybe TVERB (in discussion from v1).

If we agree to use more, TDEBUG or TVERBOSE would be better.

Kind regards,
Petr

Naming things is hard, I suppose that the least confusing is probably
the full spelling, i.e. TDEBUG. I suppose that having it one letter
longer is not a big deal.

OK, I'll wait for other feedback before sending v3 with
s/TDBUG/TDEBUG/

Kind regards,

TDEBUG sounds good to me. Also TVERB was not so bad, but I prefer the 
TDEBUG notation.
