The quilt patch titled Subject: Documentation: kdump: clean up the outdated description has been removed from the -mm tree. Its filename was documentation-kdump-clean-up-the-outdated-description.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Baoquan He <bhe@xxxxxxxxxx> Subject: Documentation: kdump: clean up the outdated description Date: Fri, 29 Mar 2024 21:28:25 +0800 After commit 443cbaf9e2fd ("crash: split vmcoreinfo exporting code out from crash_core.c"), Kconfig item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 So clean up the outdated description about CRASH_CORE and update it accordingly.
