From edbfd9112f70c34b2965580a67dad5fb306fb6c9 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 3 Nov 2017 07:02:15 -0700 Subject: Revert "workqueue: respect isolated cpus when queueing an unbound work" This reverts commit b5149873a0c299195b5346fe4dc2c5b04ae2f995. It conflicts with the following isolcpus change from the sched branch. edb9382175c3 ("sched/isolation: Move isolcpus= handling to the housekeeping code") Let's revert for now.
