This is a note to let you know that I've just added the patch titled block: move CONFIG_BLOCK guard to top Makefile to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: block-move-config_block-guard-to-top-makefile.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit ad87171b3cee02bf6549470202cf014da959d77e Author: Masahiro Yamada <masahiroy@xxxxxxxxxx> Date: Mon Sep 27 23:00:00 2021 +0900 block: move CONFIG_BLOCK guard to top Makefile [ Upstream commit 4c928904ff771a8e830773b71a080047365324a5 ] Every object under block/ depends on CONFIG_BLOCK. Move the guard to the top Makefile since there is no point to descend into block/ if CONFIG_BLOCK=n.
