...Patch #1 includes target-core setup of se_sess->sess_cmd_map + se_sess->sess_tag_pool resources at session creation time, using fabric independent code in transport_init_session_tags(). Patch #2 is the initial conversion of vhost-scsi fabric code to use per-cpu ida logic for obtaining a new tcm_vhost_cmd descriptor via vhost_scsi_get_tag() during vhost_work_fn_t->handle_kick() -> vhost_scsi_handle_vq() callback execution.

From: Nicholas Bellinger <nab at linux-iscsi.org> Hi folks, The following is the RFC-v3 series of tcm_vhost target fabric driver code currently in-flight for-3.6 mainline code. With the merge window opening soon, the tcm_vhost code has started seeing time in linux-next. The v2 -> v3 changelog from the last week is currently looking like: *) Unlock on error in tcm_vhost_drop_nexus()
