Pseudoflavor 390004 not found!

["Toralf Förster" <toralf.foerster@gmx.de>]

With current git kernel 3.9-X (since 1 or 2 days) I'm getting the messages
seen below at a user mode linux guest on which I run trinity.

On the guest I mount via NFSv4 (and in parallel via hostfs) an EXT4 fs from the host system.
The EXT4 resides within a file on a tmpfs which is mounted via loop device.

So on the hosts it looks like :
$> df -m
tmpfs               3072   135      2938   5% /mnt/ramdisk
/dev/loop0           241     5       224   3% /mnt/trinity

$ cat /etc/exports
# /etc/exports: NFS file systems being exported.  See exports(5).
/mnt/trinity    192.168.0.0/16(rw,fsid=0,insecure,no_subtree_check,async,no_root_squash)

and the UML mounts the share /mnt/trinity just onto its mount points /mnt/n22 and /mnt/nfs/n22 respectively.
And these are the messages I'm curious about :

2013-05-01T10:22:55.613+02:00 trinity kernel: gss_create: Pseudoflavor 390004 not found!
