...
Now every filesystem must provide fs->create_file_inode() for new inodes :)

Start implementing read and write support in tmpfs
...
write seems to work fine, read just hangs there, waiting.

...
This new device uses the seeded Mersenne PRNG we use in the kernel.
This device is not meant for regular userspace use, but more for userspace to seed their own PRNGs from.
If the DeviceFS is mounted at /dev, this device can be found at /dev/random.
