>Description:
puffs_vnop_inactive() does not investigate if there is dirty
data in the page cache when it issues INACTIVE.  Later, when
the dirty data is flushed, SETATTR and WRITE are issued to
the file server for a node which should have no external
references.
>How-To-Repeat:

>Fix:
Do not issue inactive before all cached operations have been completed.
