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()
