From f4d3f25aced3b493e57fd4109e2bc86f0831b23e Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Fri, 14 May 2021 17:27:36 -0700 Subject: [PATCH] docs: admin-guide: update description for kernel.modprobe sysctl When I added CONFIG_MODPROBE_PATH, I neglected to update Documentation/. It's still true that this defaults to /sbin/modprobe, but now via a level of indirection. So document that the kernel might have been built with something other than /sbin/modprobe as the initial value.
