Yes, I believe devtmpfs should be omitted. I never noticed the
kernel option for it until now :x
Since I've been playing with SystemTap, I've also noticed "debugfs"
on some systems.
Here is an updated patch with debugfs and devtmpfs:

Subject: [PATCH] mountlist: recognize more "dummy" file systems
* lib/mountlist.c (ME_DUMMY_0):
Add these dummy FS names to the list:
- "debugfs" virtual filesystem for kernel debugging
- "devpts" PTY slave filesystem
- "devtmpfs" device filesystem on top of tmpfs/ramfs
- "fusectl" control filesystem for FUSE
- "mqueue" enumerates POSIX message queues
- "rpc_pipefs" kernel <-> userspace bridge for NFS
- "sysfs" is for exporting kernel objects
- "devfs" device filesystem for Linux 2.4 and FreeBSD
