That's interesting -- this morning, I hit a ffs_valloc: dup alloc panic
following a buildworld.  I assumed it was to do with my local ACL patches,
although I have been unable to find a bug that could trigger it.  I'm
wondering if this isn't some sort of locking issue in VFS.  I managed to
trigger it in ufs_mkdir(), as I introduced a potentially location for
blocking where previously none existed, suggesting that perhaps some UFS
code is playing fast and loose with vnode locks.  This panic is
generated when FFS tries to recycle a vnode, but discovers it has a
non-zero mode, indicating that it is in use elsewhere in the system,
which should never happen.

BTW, do you have FFS_EXTATTR enabled?

Anyhow, I'm going to see if I can get it to be reproduceable here.
