Its filename is fb_defio-do-not-use-deprecated-page-mapping-index-fields-fix.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/fb_defio-do-not-use-deprecated-page-mapping-index-fields-fix.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: Lorenzo Stoakes Subject: fbdev: have CONFIG_FB_DEFERRED_IO depend on CONFIG_MMU Date: Sat, 1 Feb 2025 16:56:02 +0000 Frame buffer deferred I/O is entirely reliant on the page faulting mechanism (and thus, an MMU) to function. Express this dependency in the Kconfig, as otherwise randconfig could generate invalid configurations resulting in build errors.
