Message-ID: <20070531181923.GA9904@c2.user-mode-linux.org> Date: Thu, 31 May 2007 14:19:23 -0400 From: Jeff Dike <jdike@...toit.com> To: Zach Brown <zach.brown@...cle.com>, Ingo Molnar <mingo@...e.hu> Cc: LKML <linux-kernel@...r.kernel.org>, uml-devel <user-mode-linux-devel@...ts.sourceforge.net> Subject: [PATCH] Syslets - Fix cachemiss_thread return value cachemiss_thread should explicitly return 0 or error instead of task_ret_reg(current) (which is -ENOSYS anyway) because async_thread_helper is careful to put the return value in eax anyway. On x86_64, it looks like async_child_rip is similarly careful.
