Hello Linus, The following is the first round of target core + fabric driver updates for the freshly opened v3.6 merge window. Please go ahead and pull from: git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next This series is based on target-pending/master commit 1765fe5edcb83f53f So I ended up needing to rebase for-next last week to pick up fixes in master that for-next ended up conflicting with, but the bulk of the series has been in linux-next a number of weeks and has getting a good amount of testing. There have been lots of work in a number of areas this past round. The highlights include: *) Break out target_core_cdb.c emulation into SPC/SBC ops (hch) *) Add a parse_cdb method to target backend drivers (hch) *) Move sync_cache + write_same + unmap into spc_ops (hch) *) Use target_execute_cmd for WRITEs in iscsi_target + srpt (hch) *) Offload WRITE I/O backend submission in tcm_qla2xxx + tcm_fc (hch + nab) *) Refactor core_update_device_list_for_node() into enable/disable funcs (agrover) *) Replace the TCM processing thread with a TMR work queue (hch) *) Fix regression in transport_add_device_to_core_hba from TMR conversion (DanC) *) Remove racy, now-redundant check of sess_tearing_down with qla2xxx (roland) *) Add range checking, fix reading of data len + possible underflow in UNMAP (roland) *) Allow for target_submit_cmd() returning errors + convert fabrics (roland + nab) *) Drop bogus struct file usage for iSCSI/SCTP (viro) Thanks again to everyone who has contributed! On the new target fabric module front for-3.6, tcm_vhost is currently in RFC-v4 on the lists + queued up + waiting for ACKs from MST & Co here: http://marc.info/?l=kvm&m=134285417314176&w=2 At this point I think the vhost folks are pretty agreeable for an initial merge of this kernel code, but the vhost-scsi bits in upstream QEMU userspace code will still need to be shorted out. So because of this fact, MST has requested to mark this driver as STAGING o indicate the userspace ABI is not (yet) set in stone. Currently the last item being discussed for initial merge is if this code can just be marked as STAGING + live in drivers/vhost/, or if it should actually reside under drivers/staging/ and go upstream via the staging tree. The last -v4 series of the code keeps the initial merge in drivers/vhost/, which is easier than getting staging to depending on vhost + target-pending.. So the current plan is to send a [GIT PULL] next weekend, in order to give MST a chance to review + ACK as he returns from holiday. Otherwise if folks object, I'll move this code to drivers/staginig/tcm_vhost/ and let Greg-KH decide if he's OK to take it via staging for this round.
