Subject: [PATCH 6/8] Revert "signal: don't allow STOP on PF_IO_WORKER threads"
Date: Thu, 25 Mar 2021 18:39:29 -0600 [thread overview]
Message-ID: <20210326003928.978750-7-axboe@kernel.dk> (raw)
In-Reply-To: <20210326003928.978750-1-axboe@kernel.dk>
This reverts commit 4db4b1a0d1779dc159f7b87feb97030ec0b12597.
The IO threads allow and handle SIGSTOP now, so don't special case them
anymore in task_set_jobctl_pending().
