[LTP] [PATCH v3] Refactoring setpgid03.c test using new LTP API
Andrea Cervesato
andrea.cervesato@suse.de
Wed Feb 16 14:26:32 CET 2022
Removed TST_CHECKPOINT_INIT and replaced it with the .needs_checkpoints
LTP test feature. Simplified source code.
Signed-off-by: Andrea Cervesato <andrea.cervesato@suse.de>
---
v3 has removed wait since it's handled by library and TST_EXP_FAIL is now used.
