-Subject: [PATCH net] net: korina: Fix NAPI versus resources freeing
-
-Commit beb0babfb77e ("korina: disable napi on close and restart")
-introduced calls to napi_disable() that were missing before,
-unfortunately this leaves a small window during which NAPI has a chance
-to run, yet we just freed resources since korina_free_ring() has been
-called:
-
-Fix this by disabling NAPI first then freeing resource, and make sure
-that we also cancel the restart taks before doing the resource freeing.
-
-Fixes: beb0babfb77e ("korina: disable napi on close and restart")
