Module Name:    src
Committed By:   dyoung

Modified Files:
        src/sys/kern: kern_pmf.c

Log Message:
Do not interleave device detachment with device shutdown.  Instead, try
over and over to detach all of the devices.  Stop when we cannot detach
even a single device in a cycle.  Call shutdown hooks on all of the
devices that remain attached.

This is another step toward the detach/unmount cycle that will help us
tear down arbitrary stacks of filesystems, ccd(4), raid(4), and vnd(4).
