Pull SCSI target updates from Nicholas Bellinger:
"Things have been quiet this round with mostly bugfixes, percpu
conversions, and other minor iscsi-target conformance testing changes.
The highlights include:
- Add demo_mode_discovery attribute for iscsi-target (Thomas)
- Convert tcm_fc(FCoE) to use percpu-ida pre-allocation
- Add send completion interrupt coalescing for ib_isert
- Convert target-core to use percpu-refcounting for se_lun
- Fix mutex_trylock usage bug in iscsit_increment_maxcmdsn
- tcm_loop updates (Hannes)
- target-core ALUA cleanups + prep for v3.14 SCSI Referrals support (Hannes)
v3.14 is currently shaping to be a busy development cycle in target
land, with initial support for T10 Referrals and T10 DIF currently on
the roadmap"

Every fabric driver has to supply a se_tfo->set_fabric_sense_len()
method, just so iSCSI can return an offset of 2. However, every fabric
driver is already allocating a sense buffer and passing it into the
target core, either via transport_init_se_cmd() or target_submit_cmd().
So instead of having iSCSI pass the start of its sense buffer into the
core and then later tell the core to skip the first 2 bytes, it seems
easier for iSCSI just to do the offset of 2 when it passes the sense
buffer into the core. Then we can drop the se_tfo->set_fabric_sense_len()
everywhere, and just add a couple of lines of code to iSCSI to set the
sense data length to the beginning of the buffer right before it sends
it over the network.

srpt_handle_rdma_comp is called from kthread context and thus can execute
target_execute_cmd directly. srpt_abort_cmd sets the CMD_T_LUN_STOP

replaced with an opencoded variant of that code path. I'm still not happy

across IEEE-1394 Firewire hardware. This will be going out as a

This patch addresses a bug in srpt_handle_cmd() failure handling where
send_ioctx->kref is being leaked with the local extra reference after init,
causing the expected kref_put() in srpt_handle_send_comp() to not be the final
call to invoke srpt_put_send_ioctx_kref() -> transport_generic_free_cmd() and
perform se_cmd descriptor memory release.
It also fixes a SCF_SCSI_RESERVATION_CONFLICT handling bug where this code
is incorrectly falling through to transport_handle_cdb_direct() after
invoking srpt_queue_status() to send SAM_STAT_RESERVATION_CONFLICT status.
Note this patch is for >= v3.3 mainline code, and current lio-core.git
code has already been converted to target_submit_cmd() + se_cmd->cmd_kref usage,
and internal ioctx->kref usage has been removed. I'm including this patch
now into target-pending/for-next with a CC' for v3.3 stable.

In the target core that assumption generally is true, but some recently added

This patch adds the kernel module ib_srpt SCSI RDMA Protocol (SRP) target
implementation conforming to the SRP r16a specification for the mainline
drivers/target infrastructure.
This driver was originally developed by Vu Pham and has been optimized by
Bart Van Assche and merged into upstream LIO based on his srpt-lio-4.1
branch here:
https://github.com/bvanassche/srpt-lio/commits/srpt-lio-4.1/
This updated patch also contains the following two changes from
lio-core-2.6.git/master. One is to fix a bug with 1 >= task->task_sg[]
chained mappings in ib_srpt, and the other to convert the configfs control
plane to reference IB Port GUID and struct srpt_port directly following
mainline v4.x target_core_fabric_configfs.c convertion for ib_srpt
to work with rtslib/rtsadmin v2 code.
