Description

Basically /dev/urandom but blocks if the pool hasn't been initialized yet (same semantics as getrandom).

Contributor guide

Research direction
Review the existing `write` implementation for `FileOperations` and examine the linked issues #162 and #232 for `ioctl` and `poll`. Look for examples in the Linux kernel source for how these operations are typically implemented in Rust kernel modules.
