Subject: [PATCH] autofs: do not check for modprobe

Description: Loading autofs module is #ifdef'ed in the source, so
 there is no need to check for /proc (which is only used
 to load module) or modprobe.  Both modprobe and /proc
 are always in the fixed location so there's no need to
 check for these to start with.

Upstream-Status: Backport [1]
