[PATCH 02/19] selftests/timers: Quiet warning due to lack of return check on brk

From: John Stultz
Date: Wed Feb 25 2015 - 17:37:48 EST


The posix_timers.c test has a loop that tries to keep it in
kernel space, repeatedly calling brk(). Since its noise, and
a failure won't change what the test would do, add a unused
value to quiet the warning.
