The patch titled
Subject: vfork: kill PF_STARTING
has been removed from the -mm tree. Its filename was

------------------------------------------------------
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Subject: vfork: kill PF_STARTING
Previously it was (ab)used by utrace. Then it was wrongly used by the
scheduler code.
Currently it is not used, kill it before it finds the new erroneous user.
