Subject: [PATCH] event/cnxk: initialize work slot read cache
Date: Mon, 20 Jun 2022 13:26:16 +0200	[thread overview]
Message-ID: <20220620112616.3710246-1-vfialko@marvell.com> (raw)

Initialize gw_rdata with tag type EMPTY. Leaving tag type as
zero(ATOMIC) may cause some unnecessary head wait, if cache will be used
before the first update in dequeue/get_work functions.
