New ext2-related panic

[Andre Nathan]

Hello

I got this new ext2-related panic today:

panic: assertion: cnp->cn_flags & CNP_PDIRUNLOCK in relookup

To reproduce it: (/mnt/ext2 is an ext2fs mount point)

cd /mnt/ext2fs
mkdir -p foo/bar
mv foo/bar .  (or cd foo; mv bar ..)

i.e., trying to move a directory up one level.

The kernel dumps are at
