Linus Torvalds 141eaccd01 Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
 "Here are the target pending updates for v3.15-rc1.  Apologies in
  advance for waiting until the second to last day of the merge window
  to send these out.

  The highlights this round include:

   - iser-target support for T10 PI (DIF) offloads (Sagi + Or)
   - Fix Task Aborted Status (TAS) handling in target-core (Alex Leung)
   - Pass in transport supported PI at session initialization (Sagi + MKP + nab)
   - Add WRITE_INSERT + READ_STRIP T10 PI support in target-core (nab + Sagi)
   - Fix iscsi-target ERL=2 ASYNC_EVENT connection pointer bug (nab)
   - Fix tcm_fc use-after-free of ft_tpg (Andy Grover)
   - Use correct ib_sg_dma primitives in ib_isert (Mike Marciniszyn)

  Also, note the virtio-scsi + vhost-scsi changes to expose T10 PI
  metadata into KVM guest have been left-out for now, as there where a
  few comments from MST + Paolo that where not able to be addressed in
  time for v3.15.  Please expect this feature for v3.16-rc1"

To understand all the Linux-USB framework, you'll use these resources:

    * This source code.  This is necessarily an evolving work, and
      includes kerneldoc that should help you get a current overview.
      ("make pdfdocs", and then look at "usb.pdf" for host side and
      "gadget.pdf" for peripheral side.)  Also, Documentation/usb has
      more information.

    * The USB 2.0 specification (from www.usb.org), with supplements
      such as those for USB OTG and the various device classes.
      The USB specification has a good overview chapter, and USB
      peripherals conform to the widely known "Chapter 9".

    * Chip specifications for USB controllers.  Examples include
      host controllers (on PCs, servers, and more); peripheral
      controllers (in devices with Linux firmware, like printers or
      cell phones); and hard-wired peripherals like Ethernet adapters.

    * Specifications for other protocols implemented by USB peripheral
      functions.  Some are vendor-specific; others are vendor-neutral
      but just standardized outside of the www.usb.org team.

Here is a list of what each subdirectory here is, and what is contained in
them.

core/		- This is for the core USB host code, including the
		  usbfs files and the hub class driver ("khubd").

host/		- This is for USB host controller drivers.  This
		  includes UHCI, OHCI, EHCI, and others that might
		  be used with more specialized "embedded" systems.

gadget/		- This is for USB peripheral controller drivers and
		  the various gadget drivers which talk to them.


Individual USB driver directories.  A new driver should be added to the
first subdirectory in the list below that it fits into.

image/		- This is for still image drivers, like scanners or
		  digital cameras.
../input/	- This is for any driver that uses the input subsystem,
		  like keyboard, mice, touchscreens, tablets, etc.
../media/	- This is for multimedia drivers, like video cameras,
		  radios, and any other drivers that talk to the v4l
		  subsystem.
../net/		- This is for network drivers.
serial/		- This is for USB to serial drivers.
storage/	- This is for USB mass-storage drivers.
class/		- This is for all USB device drivers that do not fit
		  into any of the above categories, and work for a range
		  of USB Class specified devices. 
misc/		- This is for all USB device drivers that do not fit
		  into any of the above categories.
