FUJITA Tomonori f4f4e47e4a [SCSI] add residual argument to scsi_execute and scsi_execute_req
scsi_execute() and scsi_execute_req() discard the residual length
information. Some callers need it. This adds residual argument
(optional) to scsi_execute and scsi_execute_req.

James Bottomley 38582a62ec [SCSI] sr: fix test unit ready responses
Commit 210ba1d172 updated sr.c to use
the scsi_test_unit_ready() function.  Unfortunately, this has the
wrong characteristic of eating NOT_READY returns which sr.c relies on
for tray status.

Fix by rolling an internal sr_test_unit_ready() that doesn't do this.

James Bottomley 210ba1d172 [SCSI] sr: update to follow tray status correctly
Based on an original patch from: David Martin <tasio@tasio.net>

When trying to get the drive status via ioctl CDROM_DRIVE_STATUS, with
no disk it gives CDS_TRAY_OPEN even if the tray is closed.

ioctl works as expected with ide-cd driver.

Tim Schmielau cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
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).

Robert P. J. Day 5cbded585d [PATCH] getting rid of all casts of k[cmz]alloc() calls
Run this:

	#!/bin/sh
	for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.

Christoph Hellwig 6a2900b676 [PATCH] kill cdrom ->dev_ioctl method
Since early 2.4.x all cdrom drivers implement the block_device methods
themselves, so they can handle additional ioctls directly instead of going
through the cdrom layer.

Linus Torvalds f716d83033 Allocate 96 bytes for SCSI sense data reply
The SCSI layer uses SCSI_SENSE_BUFFERSIZE (96) for the sense buffer
size, even though some other code uses "sizeof(struct request_sense)"
(which is 64 bytes).  Allocate the buffer using the bigger of the two
for safety.

Christoph Hellwig a09c631121 [SCSI] sr: split sr_audio_ioctl into specific helpers
split each ioctl handled in sr_audio_ioctl into a function of it's own.
This cleans the code up nicely, and allows various places in sr_ioctl
to call these helpers directly instead of going through the multiplexer.

James Bottomley 820732b501 [SCSI] convert sr to scsi_execute_req
This follows almost the identical model to sd, except that there's one
ioctl which returns raw sense data, so it had to use scsi_execute()
instead.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
