Author: gibbs Date: Tue Sep 3 13:49:00 2013 New Revision: 255179 URL: http://svnweb.freebsd.org/changeset/base/255179 Log: sys/dev/xen/blkback/blkback.c: Initialize the request id for requests in xbb_get_resources() instead of its previous location in xbb_dispatch_io(). This guarantees that all request types (e.g. BLKIF_OP_FLUSH_DISKCACHE) have the front-end specified id recorded.
