From: Lalith Rajendran <lalithkraj@google.com> stable inclusion from stable-v5.10.150 commit ac66db1a436504159463f811b9e9864c1d2b03f1 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0XA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 3b575495ab8dbb4dbe85b4ac7f991693c3668ff5 upstream. ext4_lazyinit_thread is not set freezable. Hence when the thread calls try_to_freeze it doesn't freeze during suspend and continues to send requests to the storage during suspend, resulting in suspend failures.
