From 0a779003213b589d7b3eef72f69e19a30f603ebc Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Mon, 9 Oct 2023 15:37:51 +0200 Subject: [PATCH] netdev: make napi_schedule return bool on NAPI successful schedule Change napi_schedule to return a bool on NAPI successful schedule. This might be useful for some driver to do additional steps after a NAPI has been scheduled.
