+Subject: Revert "kernel: freezer should treat PF_IO_WORKER like PF_KTHREAD for freezing"
+
+From: Jens Axboe <axboe@kernel.dk>
+
+commit d3dc04cd81e0eaf50b2d09ab051a13300e587439 upstream.
+
+This reverts commit 15b2219facadec583c24523eed40fa45865f859f.
+
+Before IO threads accepted signals, the freezer using take signals to wake
+up an IO thread would cause them to loop without any way to clear the
+pending signal. That is no longer the case, so stop special casing
+PF_IO_WORKER in the freezer.
