Date: Sat, 16 Mar 2013 13:02:05 +0900 From: HATAYAMA Daisuke <d.hatayama@...fujitsu.com> To: vgoyal@...hat.com, ebiederm@...ssion.com, cpw@....com, kumagai-atsushi@....nes.nec.co.jp, lisa.mitchell@...com, heiko.carstens@...ibm.com, akpm@...ux-foundation.org Cc: kexec@...ts.infradead.org, linux-kernel@...r.kernel.org, zhangyanfei@...fujitsu.com Subject: [PATCH v3 14/21] kexec, elf: introduce NT_VMCORE_DEBUGINFO note type This patch introduces NT_VMCORE_DEBUGINFO to a unique note type in VMCOREINFO name, which has had no name so far. The name means that it's a kind of note type in vmcoreinfo that contains system kernel's debug information.
