Hi Linus, Here are the target updates for v3.18-rc2 code. These where originally destined for -rc1, but due to the combination of travel last week for KVM Forum and my mistake of taking the three week merge window literally, the pull request slipped.. Apologies for that. A heads-up that you'll hit one minor conflict with scsi.git, that was caught by sfr in linux-next here: http://marc.info/?l=linux-next&m=141223868207635&w=2 Please go ahead and pull from: git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next Things where reasonably quiet this round. The highlights include: - New userspace backend driver (target_core_user.ko) by Shaohua Li and Andy Grover - A number of cleanups in target, iscsi-taret and qla_target code from Joern Engel - Fix an OOPs related to queue full handling with CHECK_CONDITION status from Quinn Tran - Fix to disable TX completion interrupt coalescing in iser-target, that was causing problems on some hardware - Fix for PR APTPL metadata handling with demo-mode ACLs I'm most excited about the new backend driver that uses UIO + shared memory ring to dispatch I/O and control commands into user-space. This was probably the most requested feature by users over the last couple of years, and opens up a new area of development + porting of existing user-space storage applications to LIO. Thanks to Shaohua + Andy for making this happen. Also another honorable mention, a new Xen PV SCSI driver was merged via the xen/tip.git tree recently, which puts us now at 10 target drivers in upstream! Thanks to David Vrabel + Juergen Gross for their work to get this code merged.
