Subject: [PATCH 1/2] s390: fix checkpoint and restart compat wrappers
Date: Mon, 15 Jun 2009 12:04:43 -0500 [thread overview]
Message-ID: <20090615170443.GA14808@us.ibm.com> (raw)
They need to actually jump to the real syscall.
Though c/r from 31-bit compat is completely untested and
should maybe just be disabled for now...
