From eb7dd46c634fa5b2f2039791bd2e79343318d6e5 Mon Sep 17 00:00:00 2001 From: Sathya Perla Date: Mon, 23 Feb 2015 04:20:11 -0500 Subject: [PATCH] be2net: use a wrapper to schedule and cancel error detection task Also rename func_recovery_work/task to err_detection_work/task as error detection is the primary goal of this task while recovery is not guaranteed.
