>From the code of md-autodetect.c, it looks like it's used to create the raid device during boot. Now we use udev rules to assemble the raid. Do we still need it? What's the usage of md-autodetect? And in Kconfig, it depends on md-raid as Y when building a kernel. If we change the default to M, md-autodetect will not work anymore, right? Best Regards Xiao
