From ce63f891e1a87ae79c4325dad5f512e8d6a8a78e Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Tue, 15 Mar 2016 11:28:59 +0100 Subject: [PATCH] btrfs: transaction_kthread() is not freezable transaction_kthread() is calling try_to_freeze(), but that's just an expeinsive no-op given the fact that the thread is not marked freezable. After removing this, disk-io.c is now independent on freezer API.
