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

Many struct file_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data. In addition it'll catch accidental writes at compile time to

The file init/initramfs.c is always compiled and linked in the kernel
vmlinux even when BLK_DEV_RAM and BLK_DEV_INITRD are disabled and the
system isn't using any form of an initramfs or initrd. In this situation
the code is only used to unpack a (static) default initial rootfilesystem.
The current init/initramfs.c code. usr/initramfs_data.o compiles to a size
of ~15 kbytes. Disabling BLK_DEV_RAM and BLK_DEV_INTRD shrinks the kernel
code size with ~60 Kbytes.This patch avoids compiling in the code and data for initramfs support if
CONFIG_BLK_DEV_INITRD is not defined. Instead of the initramfs code and
data it uses a small routine in init/noinitramfs.c to setup an initial
static default environment for mounting a rootfilesystem later on in the
kernel initialisation process. The new code is: 164 bytes of size.The patch is separated in two parts:
1) doesn't compile initramfs code when CONFIG_BLK_DEV_INITRD is not set
2) changing all plaforms vmlinux.lds.S files to not reserve an area of
PAGE_SIZE when CONFIG_BLK_DEV_INITRD is not set.[deweerdt@free.fr: warning fix]

Fix http://bugzilla.kernel.org/show_bug.cgi?id=7667
This is because the packet driver tries to send down read/write BLOCK_PC
commands that don't use a bio and do not use sg lists.The right fix is to replace all the packet_command stuff in the packet
driver by scsi_execute() which needs to be lifted from scsi code to
the block code for that.Fix the bug for now. It's not the full way to a generic execute block pc
infrastcuture but fixes the bug for the time being.Signed-off-by: Christoph Hellwig

Fix a bug that only appears when AoE goes over a network card that does not
support scatter-gather. The headers in the linear part of the skb appeared
to be larger than they really were, resulting in data that was offset by 24
bytes.This patch eliminates the offset data on cards that don't support
scatter-gather or have had scatter-gather turned off. There remains an
unrelated issue that I'll address in a separate email.Fixes bugzilla #7662

This patch fixes a stupid bug. Sometime during the 2tb enhancement I ended up
replacing the macros XFER_READ and XFER_WRITE with h->cciss_read and
h->cciss_write respectively. It seemed to work somehow at least on x86_64 and
ia64. I don't know how. But people started complaining about command timeouts
on older controllers like the 64xx series and only on ia32. This resolves the
issue reproduced in our lab. Please consider this for inclusion.Thanks,

This patch sets a default raid level on a volume that either does not support
reading the geometry or reports an invalid geometry for whatever reason. We
were always setting some values for heads and sectors but never set a raid
level. This caused lots of problems on some buggy firmware. Please consider
this for inclusion.Thanks,
