Subject: WARNING: at fs/ext4/inode.c:230 ext4_evict_inode+0x41b/0x510

Hi,

seen this morning with a brand new top-of-tree kernel (as of last night) plus a
couple of patches I am working on.

Due to my changes, there is a slight chance that the problem is not due to an
upstream bug, but I think that is quite unlikely (my changes are unrelated
to file system code).

If there is anything I can help to track this down, please let me know.

Thanks,
Guenter
