I just checked the source code, and it appears that the entropy pool is alive and well and that /dev/random still waits for enough entropy to collect in the pool before providing more data for consumption.

The "wait_for_random_bytes" function is still there: https://github.com/torvalds/linux/blob/48b1320a674e1ff5de2fa...
