From e4e1600a674fc5b4fabaa578d8854db96fcc28dd Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Mon, 28 Feb 2022 13:57:57 +0100 Subject: [PATCH] random: give sysctl_random_min_urandom_seed a more sensible value commit d0efdf35a6a71d307a250199af6fce122a7c7e11 upstream. This isn't used by anything or anywhere, but we can't delete it due to compatibility. So at least give it the correct value of what it's supposed to be instead of a garbage one.
