memcg: remove extra newlines from memcg oom kill log

Commit e61734c ("cgroup: remove cgroup->name") added two extra newlines to memcg oom kill log messages. This makes dmesg hard to read and parse. The issue affects 3.15+. Example: Task in /t <<< extra beagleboard#1 killed as a result of limit of /t <<< extra beagleboard#2 memory: usage 102400kB, limit 102400kB, failcnt 274712 Remove the extra newlines from memcg oom kill messages, so the messages look like: Task in /t killed as a result of limit of /t memory: usage 102400kB, limit 102400kB, failcnt 240649 Fixes: e61734c ("cgroup: remove cgroup->name") Signed-off-by: Greg Thelen <[email protected]> Acked-by: Michal Hocko <[email protected]> Acked-by: Johannes Weiner <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
