It's a legacy ioctl which is probably not used anywhere; it's been
replaced by RNDADDENTROPY. It previously allows root to bump the
entropy estimate,

Other people who have sent me fuzzer test reproducers are able to
reproduce syzkaller logs into a simple C program. Can you explain to
me what the heck:
