The quilt patch titled Subject: proc: make config PROC_CHILDREN depend on PROC_FS has been removed from the -mm tree. Its filename was proc-make-config-proc_children-depend-on-proc_fs.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: Lukas Bulwahn <lukas.bulwahn@xxxxxxxxx> Subject: proc: make config PROC_CHILDREN depend on PROC_FS Date: Fri, 9 Sep 2022 14:25:29 +0200 Commit 2e13ba54a268 ("fs, proc: introduce CONFIG_PROC_CHILDREN") introduces the config PROC_CHILDREN to configure kernels to provide the /proc/<pid>/task/<tid>/children file. When one deselects PROC_FS for kernel builds without /proc/, the config PROC_CHILDREN has no effect anymore, but is still visible in menuconfig. Add the dependency on PROC_FS to make the PROC_CHILDREN option disappear for kernel builds without /proc/.
