blk_get_request initializes rq->cmd (rq_init does) so the users don't
need to do that.The purpose of this patch is to remove sizeof(rq->cmd) and &rq->cmd,
as a preparation for large command support, which changes rq->cmd from
the static array to a pointer. sizeof(rq->cmd) will not make sense and
&rq->cmd won't work.Signed-off-by: FUJITA Tomonori

If cdrom commands are issued to a scsi drive in most cases the buffer will be
filled via dma. This leads to bad stack corruption on non coherent platforms,
because the buffers are neither cache line aligned nor is the size a multiple
of the cache line size. Using kmalloced buffers avoids this.Signed-off-by: Thomas Bogendoerfer

This patch adds support for the GD-Rom drive, SEGA's proprietary
implementation of an IDE CD Rom for the SEGA Dreamcast. This driver
implements Sega's Packet Interface (SPI) - at least partially. It will
also read disks in SEGA's propreitary GD format.Unlike previous drivers (which were never in mainline) this uses DMA and
not PIO to read disks. It is a new driver, not a refactoring of old
drivers.Signed-off by: Adrian McMenamin

The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.[akpm@linux-foundation.org: git-drm went and changed lots of stuff]

bsg uses scsi_cmd_ioctl() for some SCSI/sg ioctl
commands. scsi_cmd_ioctl() gets a request queue from a gendisk
arguement. This prevents bsg being bound to SCSI devices that don't
have a gendisk (like OSD). This adds a request_queue argument to
scsi_cmd_ioctl(). The SCSI/sg ioctl commands doesn't use a gendisk so
it's safe for any SCSI devices to use scsi_cmd_ioctl().Signed-off-by: FUJITA Tomonori

Fix soft lockup with iSeries viocd driver, caused by eventually calling
end_that_request_first() with nr_bytes 0.Some versions of hald do an SG_IO ioctl on the viocd device which becomes a
request with hard_nr_sectors and hard_cur_sectors set to zero. Passing zero
as the number of sectors to end_request() (which calls
end_that_request_first()) causes an infinite loop when the bio is being freed.This patch makes sure that the zero is never passed. It only requires some
number larger the the request size the terminate the loop.The lockup is triggered by hald, interrogating the device.

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name. Which is
pain for caching and the proc interface never implemented.I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.Signed-off-by: Eric W. Biederman

There is no need for open files in /proc/sys/XXX to hold a reference count on
the module that provides the file to prevent module unload races. While there
is code active in the module p->used in the sysctl_table_header is
incremented, preventing the sysctl from being unregisted. Once the sysctl is
unregistered it cannot be found. Open files are also not a problem as they
revalidate the sysctl information and bump p->used before accessing module
code.So setting de->owner is unnecessary, makes for a bad example and gets in my
way of removing ctl_table->de.Signed-off-by: Eric W. Biederman

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).Signed-off-by: Tim Schmielau

It's a known fact that Windows times out commands after 7 seconds, so
drives generally try and respond if they can before that happens. We
default to 5 seconds, which sometimes is a bit too short.Jeremy Higdon reported here:
http://lkml.org/lkml/2007/1/1/145
that his drive takes longer than 5 seconds for a "read track
information" command, later confirming that it is about 6.7 seconds.So just do the sane thing and change the default command timeout to 7
seconds to avoid other surprises.Signed-off-by: Jens Axboe
