Hey Michel,

I tried running xfstests against the spf branch, and I've noticed it's
causing regression for generic/619.  It's failing due to a umount
failure due to a busy mount point:

QA output created by 619
umount: /vdc: target is busy.

I haven't had a chance to investigate, but I thought I should let you know.q

Cheers,

					- Ted
