I've been using unionfs for more than a year now (to keep my local source
tree changes separate from the "official" tree) and have had no problems
other than an occassional (once a month or so) panic. Seems that when
the daily cron task kicks off, I sometimes get a panic about "cleaned
vnode isn't". Never seems to cause any file system corruption, though.
I've also made some changes recently to permit the unionfs code to
actually work in its lkm form. These changes have just yesterday been
submitted as a pr, so I have no idea when (or if) they'll make it into
the official sources.
