Module Name: src
Committed By: tron
Date: Sat May 28 15:24:49 UTC 2011
Modified Files:
src/distrib/sets/lists/tests: mi
src/tests/kernel: Makefile
Added Files:
src/tests/kernel: t_pollts.c
Log Message:
Add two test cases for pollts(2):
- The first tests basic functionality e.g. timeouts and correct events.
- The second tests whether pollts(2) correctly restores the signal mask.
This test currently fails because of PR kern/44986.
