Subject: [PATCH] libfrog: fs_table_lookup_mount should realpath the argument
Git-commit: be66eb8ef581ae50ec9fe6ff8a95a58fe62c2b45
Patch-mainline: v4.16.0-rc1
References: bsc#1181299
Call realpath on the dir argument so that we're comparing canonical
paths when looking for the mountpoint. This fixes the problem where
'/home/' doesn't match '/home' even though they refer to the same thing.
