To compile this file system support as a module, choose M here. The module will be called ext4dev. Be aware, however, that the filesystem of your root partition (the one containing the directory /) cannot be compiled as a module, and so this could be dangerous. Why can't this be compiled as a module when / is ext4? There are a lot of people out there having no filesystem code included in the kernel at all (includes at least SUSE users using the default vendor kernel), but instead have them as modules in their initramfss (what's the proper plural of initramfs?). What is it that makes ext4 different? -`J' -- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
