The patch titled Subject: mm/mm_init.c: move build check on MAX_ZONELISTS out of ifdef has been added to the -mm mm-unstable branch. Its filename is mm-mm_initc-move-build-check-on-max_zonelists-out-of-ifdef.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-mm_initc-move-build-check-on-max_zonelists-out-of-ifdef.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: Wei Yang <richard.weiyang@xxxxxxxxx> Subject: mm/mm_init.c: move build check on MAX_ZONELISTS out of ifdef Date: Wed, 19 Jun 2024 01:06:10 +0000 Current check on MAX_ZONELISTS is wrapped in CONFIG_DEBUG_MEMORY_INIT, which may not be triggered all the time. Let's move it out to a more general place.
