From b6cfbecafbd2ee9407844122c928ff5147747a86 Mon Sep 17 00:00:00 2001 From: David Howells Date: Tue, 5 Jun 2018 10:54:24 +0100 Subject: afs: Handle CONFIG_PROC_FS=n The AFS filesystem depends at the moment on /proc for configuration and also presents information that way - however, this causes a compilation failure if procfs is disabled. Fix it so that the procfs bits aren't compiled in if procfs is disabled. This means that you can't configure the AFS filesystem directly, but it is still usable provided that an up-to-date keyutils is installed to look up cells by SRV or AFSDB DNS records.
