From be66eb8ef581ae50ec9fe6ff8a95a58fe62c2b45 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 26 Mar 2018 21:27:28 -0500 Subject: [PATCH] libfrog: fs_table_lookup_mount should realpath the argument 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. Signed-off-by: Darrick J.
