Author: smh Date: Sat Mar 14 17:35:04 2015 New Revision: 279996 URL: https://svnweb.freebsd.org/changeset/base/279996 Log: Allow zvol_geom_worker to process BIO_DELETE's If zvol_geom_start is called with a BIO_DELETE from a thread which can sleep it queues it for later processing by the zvol_geom_worker. The zvol_geom_worker didn't have a delete case so would simply loose the bio hence preventing the original caller from every completing. In addition an other unknown types would suffer the same fate. Allow zvol_geom_worker to process BIO_DELETE's via zvol_strategy and return unsupported for all unknown bio types.
