Subject[PATCH 0/1] Revert "kmod: handle UMH_WAIT_PROC from system unbound workqueue"
Hello,

I noticed by accident the kworker zombies on my testing machine.
Can't reproduce (although I think it won't be hard to make a
test-case), but I think the reason is clear, see the changelog.

We could fix this by using kthread_create() if !UMH_WAIT_PROC,
but imo it would be better to revert this change at least for
now. If we really want to avoid the extra kernel_thread(), we
can make another patch which also avoids sys_wait4() and the
games with SIGCHLD; we can rely on wait_chldexit.

Oleg.
