Commit-ID: f80f749132165fb083865e51afd65cf0f05dcd62 Gitweb: http://git.kernel.org/tip/f80f749132165fb083865e51afd65cf0f05dcd62 Author: Seiji Aguchi <sei...@hd...> AuthorDate: Tue, 15 May 2012 17:35:09 -0400 Committer: Ingo Molnar <mi...@ke...> CommitDate: Fri, 18 May 2012 10:07:37 +0200 kdump: Execute kmsg_dump(KMSG_DUMP_PANIC) after smp_send_stop() This patch moves kmsg_dump(KMSG_DUMP_PANIC) below smp_send_stop(), to serialize the crash-logging process via smp_send_stop() and to thus retrieve a more stable crash image of all CPUs stopped.
