While accessing a unusual usb storage (ums-alauda, ums-cypress, ...),
the module reference count is not incremented. Because these drivers
allocate scsi hosts with usb_stor_host_template defined in usb-storage
module. So these drivers always can be unloaded.
This fixes it by preparing scsi host template which is initialized
at module_init() for each ums-* driver. In order to minimize the
difference in ums-* drivers, introduce module_usb_stor_driver() helper
macro which is same as module_usb_driver() except that it also
initializes scsi host template.

The SCSI standard defines 64-bit values for LUNs, and large arrays
employing large or hierarchical LUN numbers become more and more
common.
So update the linux SCSI stack to use 64-bit LUN numbers.

Use a more current logging style with dev_printk
where possible.
o Convert uses of US_DEBUGP to usb_stor_dbg
o Add "struct us_data *" to usb_stor_dbg uses
o usb_stor_dbg now uses struct device */dev_vprint_emit
o Removed embedded function names
o Coalesce formats
o Remove trailing whitespace
o Remove useless OOM messages
o Remove useless function entry/exit logging
o Convert some US_DEBUGP uses to dev_info and dev_dbg
Object size is slightly reduced when debugging
is enabled, slightly increased with no debugging
because some initialization and removal messages
are now always emitted.

libusual. Now we have only the usb-storage driver as the only driver in

This converts the drivers in drivers/usb/* to use the

Added bonus is that it removes some unneeded kernel log messages about

This patch (as1207) converts usb-storage's sddr09 subdriver into a
separate module.
An unexpected complication arises because of DPCM devices, in which
one LUN uses the sddr09 transport and one uses the standard CB
transport. Since these devices can be used even when
USB_STORAGE_SDDR09 isn't configured, their entries in unusual_devs.h
require special treatment. If SDDR09 isn't configured then the
entries remain in unusual_devs.h; if it is then the entries are
present in unusual_sddr09.h instead.

The DPCM subdriver is a little peculiar, in that it's meant to support
devices where LUN 0 is Compact Flash and uses the CB transport whereas
LUN 1 is SmartMedia and uses the SDDR09 transport. Thus DPCM isn't
really a transport in itself; it's more like a demultiplexer.
Much of the DPCM code is part of the SDDR09 subdriver already, and the
remaining part is fairly small. This patch (as1182) moves that extra
piece into sddr09.c, thereby eliminating dpcm.c. Also eliminated is
the Kconfig entry for DPCM support; it is now listed as part of the
SDDR09 entry.
In order to make sure that the semantics are the same as before, each
unusual_devs entry for DPCM is now present twice: once with DPCM
support if SDDR09 is configured (as before), and once with the
SINGLE_LUN flag and CB support otherwise.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
