https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v3.10.22013-01-08T18:00:44Zcgroups: fix cgroup_event_listener error handling2013-01-08T18:00:44ZGreg Thelengthelen@google.com2013-01-07T19:50:17Zurn:sha1:799105d514384b80cbe3182dbcb4ed30aa07e1f5
The error handling in cgroup_event_listener.c did not correctly deal
with either an error opening either <control_file> or
cgroup.event_control. Due to an uninitialized variable the program
exit code was undefined if either of these opens failed.
This patch simplifies and corrects cgroup_event_listener.c error
handling by:
1. using err*() rather than printf(),exit()
2. depending on process exit to close open files
With this patch failures always return non-zero error.

cgroups: move cgroup_event_listener.c to tools/cgroup2013-01-07T17:41:28ZGreg Thelengthelen@google.com2013-01-04T21:05:17Zurn:sha1:92e015b1cfc24e3cb072385f25171b8599cc7ef3
Move the cgroup_event_listener.c tool from Documentation into the new
tools/cgroup directory.
This change involves wiring cgroup_event_listener.c into the tools/
make system so that is can be built with:
$ make tools/cgroup
