From: Oren Laadan on 1 May 2010 10:40 We need to use this value in the checkpoint/restart code and would like to have a constant instead of a magic '3'. Changelog: Jan 20: . Define s390x sys_restart wrapper Mar 30: . Add CHECKPOINT_SUPPORT in Kconfig (Nathan Lynch) Mar 03: . Picked up additional use of magic '3' in ptrace.h Cc: linux-s390(a)vger.kernel.org Signed-off-by: Dan Smith <danms(a)us.ibm.com> Acked-by: Serge E. Hallyn <serue(a)us.ibm.com> Tested-by: Serge E.
