Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending

2016-08-05T00:04:37+00:00

Pull SCSI target updates from Nicholas Bellinger:
 "The most notable item is IBM virtual SCSI target driver, that was
  originally ported to target-core back in 2010 by Tomo-san, and has
  been brought forward to v4.x code by Bryant Ly, Michael Cyr and co
  over the last months.

  Also included are two ORDERED task related bug-fixes Bryant + Michael
  found along the way using ibmvscsis with AIX guests, plus a few
  miscellaneous target-core + iscsi-target bug-fixes with associated
  stable tags"

fcoe: implement FIP VLAN responder

2016-07-20T23:49:41+00:00

When running in VN2VN mode there is no central instance which would send
out any FIP VLAN discovery notifications. So this patch adds a new sysfs
attribute 'fip_vlan_responder' which will activate a FIP VLAN discovery
responder.

ibmvscsis: Initial commit of IBM VSCSI Tgt Driver

2016-07-20T08:15:43+00:00

This driver is a pick up of the old IBM VIO scsi Target Driver
that was started by Nick and Fujita 2-4 years ago.
http://comments.gmane.org/gmane.linux.scsi/90119

The driver provides a virtual SCSI device on IBM Power Servers.

This patch contains the fifth version for an initial merge of the
tcm ibmvscsis driver. More information on this driver and config
can be found:

scsi: remove the disable_blk_mq host flag

2016-07-15T19:11:20+00:00

We've had scsi-mq for 2.5 years now, so we can remove the unused flag to
disable the code on a per-host basis that was put in for unexpected
emergencies during bringup.

scsi: remove current_cmnd field from struct scsi_device

2016-07-14T02:33:23+00:00

The field is only used by the 53c700 driver, so move it into the
driver-private device data instead of having it in the common structure.

fcoe: use enum for fip_mode

2016-07-14T02:05:28+00:00

The FIP mode is independent on the FIP state machine, so use a separate
enum for that instead of overloading it with state machine values.

fcoe: convert to kworker

2016-07-13T03:16:31+00:00

The driver creates its own per-CPU threads which are updated based on
CPU hotplug events. It is also possible to use kworkers and remove some
of the kthread infrastrucure.

The code checked ->thread to decide if there is an active per-CPU
thread. By using the kworker infrastructure this is no longer
possible (or required). The thread pointer is saved in `kthread' instead
of `thread' so anything trying to use thread is caught by the
compiler. Currently only the bnx2fc driver is using struct fcoe_percpu_s
and the kthread member.

After a CPU went offline, we may still enqueue items on the "offline"
CPU. This isn't much of a problem. The work will be done on a random
CPU. The allocated crc_eof_page page won't be cleaned up. It is probably
expected that the CPU comes up at some point so it should not be a
problem. The crc_eof_page memory is released of course once the module
is removed.

This patch was only compile-tested due to -ENODEV.

lib: scatterlist: move SG pool code from SCSI driver to lib/sg_pool.c

2016-04-15T20:53:14+00:00

Now it's ready to move the mempool based SG chained allocator code from
SCSI driver to lib/sg_pool.c, which will be compiled only based on a Kconfig
symbol CONFIG_SG_POOL.

SCSI selects CONFIG_SG_POOL.
