Hi,
Can a pseudo block device create using mknod be used to hold metadata
and cached blocks ?
Thank you,

Hi
mknod doesn't create any devices, it creates a named REFERENCE to a
device, not the device itself. The device itself is specified by major and
minor number, and it must already exist, mknod doesn't create it.
Generally, you don't need to use mknod because on any modern Linux system,
references to devices are created automatically by udev in the /dev/
directory.
