Subject: ksmbd: Add missing set_freezable() for freezable kthread
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8fb7b723924cc9306bc161f45496497aec733904;p=linux.git

ksmbd: Add missing set_freezable() for freezable kthread

The kernel thread function ksmbd_conn_handler_loop() invokes
the try_to_freeze() in its loop. But all the kernel threads are
non-freezable by default. So if we want to make a kernel thread to be
freezable, we have to invoke set_freezable() explicitly.
