From 1e4cf0d3d072173ee70757ee4aec11b2839705f9 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 25 Mar 2021 18:23:44 -0600 Subject: Revert "signal: don't allow STOP on PF_IO_WORKER threads" This reverts commit 4db4b1a0d1779dc159f7b87feb97030ec0b12597. The IO threads allow and handle SIGSTOP now, so don't special case them anymore in task_set_jobctl_pending().
