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()

From: Nicholas Bellinger <nab at linux-iscsi.org> Hi MST, Greg-KH & Co, The following is -v4 of the in-flight TCM vhost fabric driver for-3.6 code. This series has been rebased into target-pending.git/for-next-merge this evening, and the changelog over the last days from v3 -> v4 has been: *) Rename vhost_vring_target -> vhost_scsi_target (mst + nab) *) Use TRANSPORT_IQN_LEN
