From b0f970c50d439df46ade159950201faba36da10b Mon Sep 17 00:00:00 2001 From: Baoquan He Date: Fri, 29 Mar 2024 21:28:25 +0800 Subject: Documentation: kdump: clean up the outdated description After commit 443cbaf9e2fd ("crash: split vmcoreinfo exporting code out from crash_core.c"), Kconfig item CRASH_CORE has gone away in kernel. Items VMCORE_INFO and CRASH_RESERVE are used instead. So clean up the outdated description about CRASH_CORE and update it accordingly.
