    Subject[PATCH 6.0 137/862] ext4: make ext4_lazyinit_thread freezable
    Date
    From: Lalith Rajendran <lalithkraj@google.com>

    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.
