Subject: cgroup/pids: Remove superfluous zeroing
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=15b8b9ab5081d8dce9aa27a594ba4db2c29cefc0;p=linux.git

cgroup/pids: Remove superfluous zeroing

Atomic counters are in kzalloc'd struct. They are zeroed already and
atomic64_t does not need special initialization
(cf kernel/trace/trace_clock.c:trace_counter).
