Subject: ext4: make ext4_lazyinit_thread freezable
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3b575495ab8dbb4dbe85b4ac7f991693c3668ff5;p=linux.git

ext4: make ext4_lazyinit_thread freezable

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.
