Because Good catch, I tried it, for 4.4: 2664K -> 2680K 16K has increased, the similar to 4.1 (2572 -> 2588), neither of them has /proc/sys. I will send patches for updating the config, Bruce can decide whether merge them or not. // Robert > this would pave way to enable busybox-mdev for device management among other things you could do > with sysctls > >> >>> >>> And: >>> $ runqemu qemux86 ramfs >>> works well.
