Subject: Re: [PATCH RFC] random: fix syzkaller fuzzer test int overflow

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:

> r3 = syz_open_dev$urandom(&(0x7f000000a000)="2f6465762f7572616e646f6d00", 0x0, 0x0)

means?
