[PATCH 0/7] SCST: A Generic SCSI Target Subsystem

[PATCH 0/7] SCST: A Generic SCSI Target Subsystem

[Bart Van Assche]

During LinuxCon 2010 the following acceptance criteria have been defined for
an in-kernel storage target:

    1. Being a drop in replacement for STGT (the current
       in-kernel target mode driver), since only a single
       SCSI target infrastructure is desired.

    2. Using a modern sysfs based control and configuration plane.

    3. That the code was reviewed as clean enough for inclusion.

We believe that SCST meets (1) and (2), and hereby kindly ask either to
review the SCST code further or to merge it in the upstream kernel.

The current patch set consists of seven patches:

0001-block-Add-blk_rq_map_kern_sg.patch
0002-SCSI-scst-Add-SCST-core.patch
0003-SCSI-scst-Add-scst_local-driver.patch
0004-SCSI-scst-Add-SRP-target-driver.patch
0005-SCSI-ibmvstgt-Port-from-tgt-to-SCST.patch
0006-SCSI-tgt-Removal.patch
0007-SCSI-tgt-Defconfig-cleanup.patch

The most important changes since the previous time SCST was posted as a
patch set (http://lkml.org/lkml/2010/10/1/140) are:
- Rewrote the SCST sysfs interface such that it uses the bus/driver/device
  infrastructure instead of creating kernel objects in /sys/kernel/scst_tgt.
- Completed porting of the ibmvstgt driver.

This patch set is also available in the scst branch of this git repository:

git://git.kernel.org/pub/scm/linux/kernel/git/bvanassche/scst.git

or alternatively, via the kernel.org git web interface on the same repository:

Note: testing the ibmvstgt driver wouldn't have been possible without
the test setup made available by IBM. We are grateful for the
resources provided by IBM and to anyone who was involved in making
that test setup available. Also, Fujita's clean and well-structured
libsrp/ibmvstgt code was an excellent basis to start from in that
porting effort.
