[Krzysztof Kozlowski]

Hi,

Changes since v4:
1. Drop applied patches.
2. Add patch 1/3 moving code to lib.
3. Change limit 500->50 in patch 3/3.

Changes since v3:
1. Adjust subject of patch 2/4.
2. Don't use TEST() macro in 2/4.
3. Remove debug messages in 2/4.
4. Return unsigned int in get_session_uid() as it cannot fail in 2/4.

Changes since v2:
1. Resend due to messed up previous submission.

Changes since v1:
1. Move the code reading cgroups session limit to lib/tst_pid.c to
   existing tst_get_free_pids_().
2. Allow reading session limits from cgroups v2.
3. Add patch 1/4 - typo fix.
4. Add patch 4/4 with the buffer/reserve of pids.

Best regards,
Krzysztof
