Subject: freezer: take kernel_execve into consideration
From: Rafael J. Wysocki <rjw@xxxxxxx>
Kernel threads can become userland processes by calling kernel_execve(). In
particular, this may happen right after
try_to_freeze_tasks(FREEZER_USER_SPACE) has returned, so try_to_freeze_tasks()
needs to take userspace processes into consideration even if it is called with
FREEZER_KERNEL_THREADS.
