[LTP] [PATCH 1/1] lib/tst_pid.c: Count used pid by traversing /proc

[Petr Vorel]

Hi Leo,

> Use "ps -eT | wc -l" to calculate the number of used pid
> could have an incorrectly larger result because "ps -eT"
> may list the same pid multiple times (with different SPID).

> Instead, we could count used pid by traversing /proc
> directory and count the subdirectories that have name
> composed of digits.

> Increase PIDS_RESERVED to avoid fork failure.

Thank you!
Waiting little longer before merging to give others change to have look.
