Having this compiled in is *probably* not what to look for. Rather people should seek for actual *usage* of these features. I use the deadline scheduler. root@marc:~ # egrep "(BLK_WBT|IOSCH)" /boot/config-4.19.5loc64 CONFIG_BLK_WBT=y CONFIG_BLK_WBT_SQ=y CONFIG_BLK_WBT_MQ=y CONFIG_IOSCHED_NOOP=y CONFIG_IOSCHED_DEADLINE=y CONFIG_IOSCHED_CFQ=y CONFIG_CFQ_GROUP_IOSCHED=y CONFIG_DEFAULT_IOSCHED="deadline" CONFIG_MQ_IOSCHED_DEADLINE=y CONFIG_MQ_IOSCHED_KYBER=y CONFIG_IOSCHED_BFQ=y # CONFIG_BFQ_GROUP_IOSCHED is not set Could someone gather a list of what actually is in .configs but is relevant/irrelevant? I don't want to do is but I'm not really sure to not mess is up. I mean there was "DAX enabled in the .config" talked about but I have it compiled-in but I'm not actually using is.
