Its filename was init-kconfig-move-more-items-into-the-expert-menu.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: Randy Dunlap Subject: init/Kconfig: move more items into the EXPERT menu Date: Thu, 7 Dec 2023 20:58:19 -0800 KCMP, RSEQ, CACHESTAT_SYSCALL, and PC104 depend on EXPERT but not shown in the EXPERT menu. Move some lines around so that they are displayed in the EXPERT menu. Drop one useless comment. Change "enabled" to "enable" for DEBUG_RSEQ.
