------------------------------------------------------
From: Tetsuo Handa <[email protected]>
Subject: kthread: fix return value of kthread_create() upon SIGKILL.
786235eeb ("kthread: make kthread_create() killable") meant for allowing
kthread_create() to abort as soon as killed by the OOM-killer. But
returning -ENOMEM is wrong if killed by SIGKILL from userspace. Change
kthread_create() to return -EINTR upon SIGKILL.
