From a4e186693cbe43b88ec577be9859276c42d16b3f Mon Sep 17 00:00:00 2001 From: Maciej Fijalkowski Date: Tue, 25 Jan 2022 17:04:39 +0100 Subject: [PATCH] ice: Remove likely for napi_complete_done Remove the likely before napi_complete_done as this is the unlikely case when busy-poll is used. Removing this has a positive performance impact for busy-poll and no negative impact to the regular case.
