Subject: [PATCH 09/17] scope: no memset() needed after __alloc_scope()
Date: Mon, 13 Apr 2020 18:15:57 +0200 [thread overview]
Message-ID: <20200413161605.95900-10-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20200413161605.95900-1-luc.vanoostenryck@gmail.com>
When starting some scopes, the newly allocated struct is
memset'ed with zero but this is unneeded since the allocator
always returns zeroed memory.
Remove the unneeded call to memset().
