Its filename is loongarch-crash-wrap-crash-dumping-code-into-crash-related-ifdefs.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/loongarch-crash-wrap-crash-dumping-code-into-crash-related-ifdefs.patch This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Baoquan He Subject: loongarch, crash: wrap crash dumping code into crash related ifdefs Date: Fri, 19 Jan 2024 22:52:41 +0800 Now crash codes under kernel/ folder has been split out from kexec code, crash dumping can be separated from kexec reboot in config items on loongarch with some adjustments. Here wrap up crash dumping codes with CONFIG_CRASH_DUMP ifdeffery, and use IS_ENABLED(CONFIG_CRASH_RESERVE) check to decide if compiling in the crashkernel reservation code.
