[arch-general] Opening symlinks in tmpfs as root fails!

[Mohammad_AlSaleh]

Hello.

I just came across some weird behavior.

A small testcase:

cd /tmp # should be tmpfs
touch tfile
ln -s tfile tlink
cat tlink

When cat executes, it returns with success(0). But, if cat is executed
as root, it fails with a permission denied error.

What's really happening is, the open() syscall fails with EACCESS when
the file is a symlink in a tmpfs-mounted dir. But only fails when run
as root!

I'm assuming this is a bug. Can anyone confirm it?
