-Subject: [PATCH 3/6] Linux 4.2: total_link_count is no longer accessible
-
-The value is now stored in the nameidata structure which
-is private to fs/namei.c, so we can't modify it here.
-
-The effect is that using a path that contains 40+ directories
-may fail with ELOOP, depending on which directories in the
-path were previously used. After a directory is accessed once
-its D_AUTOMOUNT flag is reset and it will no longer count
-against the symlink limit in later path lookups.
