This makes sense by default but I do see a point in allowing it for testing purposes --- specifically, it allows us to verify that bigalloc works on architectures such as PowerPC and Itanium where page size is greater than the 4k block size. So maybe a developer mode set via mke2fs.conf? Another option would be to enforce that we only support bigalloc file systems where the blocksize == pagesize, but that means we wouldn't be able to mount 4k bigalloc file systems on architectures with a 8k or 16k page size. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
