From 696249132158014d594896df3a81390616069c5c Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Mon, 26 Oct 2015 15:06:19 +0900 Subject: [PATCH] btrfs: clear PF_NOFREEZE in cleaner_kthread() cleaner_kthread() kthread calls try_to_freeze() at the beginning of every cleanup attempt. This operation can't ever succeed though, as the kthread hasn't marked itself as freezable. Before (hopefully eventually) kthread freezing gets converted to fileystem freezing, we'd rather mark cleaner_kthread() freezable (as my understanding is that it can generate filesystem I/O during suspend).
