Hi, This patch is a new version by Seto-san's comment. Changelog since v1: * Remove the check code other than kexec_crash_image from kexec_should_crash() because a kexec cannot crash if there is no image. This patch enables a kdump if 2nd-kernel is loaded. (The patch is based on linux-2.6.31-rc2.) Now, a kdump on oops is enabled if a kernel parameter "oops=panic" is specified and 2nd-kernel is loaded. I think that a kdump should be enabled regardless of "oops=panic" if 2nd-kernel is loaded, because a system administrator loads 2nd-kernel for enabling a kdump. * Reference The discussion about this patch http://lists.infradead.org/pipermail/kexec/2009-July/003417.html http://lists.infradead.org/pipermail/kexec/2009-July/003433.html Thanks Ken'ichi Ohmichi Signed-off-by: Ken'ichi Ohmichi <oomichi at mxs.nes.nec.co.jp> Acked-by: Simon Horman <horms at verge.net.au> --- --- a/kernel/kexec.c 2009-07-08 12:30:26.000000000 +0900 +++ b/kernel/kexec.c 2009-07-13 13:49:03.000000000 +0900 @@ -57,7 +57,7 @@ struct resource crashk_res = { int kexec_should_crash(struct task_struct *p) { - if (in_interrupt() || !p->pid || is_global_init(p) || panic_on_oops) + if (kexec_crash_image) return 1; return 0; }
