Warner Losh d9a7a61b2b Hold the reference count until the CCB is released ... When a disk disappears and the periph is invalidated, any I/Os that are pending with the controller can cause a crash when they complete. Move to holding the softc reference count taken in dastart() until the I/O is complete rather than only until xpt_action() returns. (This approach was suggested by Ken Merry.) This extends the method used in da to ada, nda, and mda. Sponsored by: Netflix Submitted by: Chuck Silvers		2018-05-15 22:22:10 +00:00
