From e2c614e68acac324241c79b1357e03cea94495d0 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 29 Jul 2020 19:11:00 -0700 Subject: [PATCH] random32: remove net_rand_state from the latent entropy gcc plugin It turns out that the plugin right now ends up being really unhappy about the change from 'static' to 'extern' storage that happened in commit d1b61c3d6f0c ("random32: update the net random state on interrupt and activity"). This is probably a trivial fix for the latent_entropy plugin, but for now, just remove net_rand_state from the list of things the plugin worries about.
