From a4d94ff8aa864c05b33c2de1f8c5d0176d7a4b63 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Thu, 20 Sep 2012 09:28:25 -0400 Subject: um: kill thread->forking we only use that to tell copy_thread() done by syscall from that done by kernel_thread(). However, it's easier to do simply by checking PF_KTHREAD in thread flags. Merge sys_clone() guts for 32bit and 64bit, while we are at it...
