Subject[PATCH 1/6] perf list: Fix exit value
From: Stephane Eranian <>

This patch fixes an issue with the exit value of perf list:

$ perf list; echo $?

perf list returns an error exit code even though there is no error.

There was a stray exit(129) in print_events(). This patch removes this

$ perf list; echo $?
