Author: mav Date: Fri Oct 2 20:09:16 2015 New Revision: 288520 URL: https://svnweb.freebsd.org/changeset/base/288520 Log: MFC r279996 (by smh): 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.
