Subject: [PATCH v4 1/6] cgroup/pids: Remove superfluous zeroing
Date: Tue, 16 Apr 2024 16:20:09 +0200	[thread overview]
Message-ID: <20240416142014.27630-2-mkoutny@suse.com> (raw)
In-Reply-To: <20240416142014.27630-1-mkoutny@suse.com>

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).
