The quilt patch titled Subject: zram: ZRAM_DEF_COMP should depend on ZRAM has been removed from the -mm tree. Its filename was zram-zram_def_comp-should-depend-on-zram.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx> Subject: zram: ZRAM_DEF_COMP should depend on ZRAM Date: Tue, 5 Nov 2024 12:50:35 +0100 When Compressed RAM block device support is disabled, the CONFIG_ZRAM_DEF_COMP symbol still ends up in the generated config file: CONFIG_ZRAM_DEF_COMP="unset-value" While this causes no real harm, avoid polluting the config file by adding a dependency on ZRAM.
