From 9ca0652596bd924a4023db6b429a0aaaea629826 Mon Sep 17 00:00:00 2001 From: David Howells Date: Tue, 9 Jun 2020 16:15:45 +0100 Subject: afs: Fix use of BUG() Fix afs_compare_addrs() to use WARN_ON(1) instead of BUG() and return 1 (ie. srx_a > srx_b). There's no point trying to put actual error handling in as this should not occur unless a new transport address type is allowed by AFS. And even if it does, in this particular case, it'll just never match unknown types of addresses. This BUG() was more of a 'you need to add a case here' indicator.
