I executed it in accordance with your process and run mount_ext4_ram.sh. The result is that mkfs can be mounted but cannot be mounted. An error occurs when mounting.
I install the 4.7.2 kernel that you provide, I cd ramdrive to make, and into ramdrive_timing to make, then to frontend/kernel/ to make. then run mount_ext4_ram.sh. Is there something wrong with my steps？Thank you~
