Subject: [PATCH v1] Benchtests: move 'alloc_bufs' from loop in bench-memset.c
Date: Sat, 5 Feb 2022 03:10:44 -0600 [thread overview]
Message-ID: <20220205091044.2014455-1-goldstein.w.n@gmail.com> (raw)
One buf allocation is sufficient. Calling `alloc_bufs' in the loop
just adds unnecessary syscall overhead.
