Subject: [PATCH v2 09/18] rtla: Remove redundant memset after calloc
Date: Tue, 6 Jan 2026 08:49:45 -0300 [thread overview]
Message-ID: <20260106133655.249887-10-wander@redhat.com> (raw)
In-Reply-To: <20260106133655.249887-1-wander@redhat.com>
The actions struct is allocated using calloc, which already returns
zeroed memory. The subsequent memset call to zero the 'present' member
is therefore redundant.
