From e7ed6473c2c8c4e45dd861bfa06e96189b11d8db Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 6 Nov 2023 18:00:08 +0800 Subject: [PATCH] crypto: jitterentropy - Hide esoteric Kconfig options under FIPS and EXPERT As JITTERENTROPY is selected by default if you enable the CRYPTO API, any Kconfig options added there will show up for every single user. Hide the esoteric options under EXPERT as well as FIPS so that only distro makers will see them.
