Jens Axboe c00895ab2f [PATCH] Remove ->waiting member from struct request
As the comments indicates in blkdev.h, we can fold it into ->end_io_data
usage as that is really what ->waiting is. Fixup the users of
blk_end_sync_rq().

Jens Axboe 4aff5e2333 [PATCH] Split struct request ->flags into two parts
Right now ->flags is a bit of a mess: some are request types, and
others are just modifiers. Clean this up by splitting it into
->cmd_type and ->cmd_flags. This allows introduction of generic
Linux block message types, useful for sending generic Linux commands
to block devices.

Daniel Walker dcd9637961 [PATCH] idetape gcc 4.1 warning fix
In both the read and write cases it will return an error if
copy_{from/to}_user faults.  However, I let the driver try to read/write as
much as it can just as it normally would , then finally it returns an error
if there was one.  This was the most straight forward way to handle the
error , since there isn't a clear way to clean up the buffers on error .

I moved retval in idetape_chrdev_write() down into the actual code blocks
since it's really once used there, and it conflicted with my ret variable.

Fixes the following warning,

drivers/ide/ide-tape.c: In function ‘idetape_copy_stage_from_user’:
drivers/ide/ide-tape.c:2662: warning: ignoring return value of ‘copy_from_user’, declared with attribute warn_unused_result

Kay Sievers 263756ec22 [PATCH] ide: MODALIAS support for autoloading of ide-cd, ide-disk, ...
IDE: MODALIAS support for autoloading of ide-cd, ide-disk, ...

Add MODULE_ALIAS to IDE midlayer modules: ide-disk, ide-cd, ide-floppy and
ide-tape, to autoload these modules depending on the probed media type of
the IDE device.

It is used by udev and replaces the former agent shell script of the hotplug
package, which was required to lookup the media type in the proc filesystem.
Using proc was racy, cause the media file is created after the hotplug event
is sent out.

The module autoloading does not take any effect, until something like the
following udev rule is configured:
  SUBSYSTEM=="ide",  ACTION=="add", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe $env{MODALIAS}"

The module ide-scsi will not be autoloaded, cause it requires manual
configuration. It can't be, and never was supported for automatic setup in
the hotplug package. Adding a MODULE_ALIAS to ide-scsi for all supported
media types, would just lead to a default blacklist entry anyway.

  $ modinfo ide-disk
  filename:       /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko
  description:    ATA DISK Driver
  alias:          ide:*m-disk*
  license:        GPL
  ...

  $ modprobe -vn ide:m-disk
  insmod /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko

  $ cat /sys/bus/ide/devices/0.0/modalias
  ide:m-disk

It also adds attributes to the IDE device:
  $ tree /sys/bus/ide/devices/0.0/
  /sys/bus/ide/devices/0.0/
  |-- bus -> ../../../../../../../bus/ide
  |-- drivename
  |-- media
  |-- modalias
  |-- power
  |   |-- state
  |   `-- wakeup
  `-- uevent

  $ cat /sys/bus/ide/devices/0.0/{modalias,drivename,media}
  ide:m-disk
  hda
  disk

Will Dyson d5dee80ad6 [PATCH] add sysfs support for ide tape
I was recently given an old Travan tape drive and asked to do something
useful with it.  The ide-scsi + st (+serverworks ide controller) combo
results in a hard lockup of the machine which I have not had the energy to
debug, so I turned to ide-tape (which seems to work).  The system in
question debian stable, using udev to manage /dev.

The following patch to ide-tape.c allows udev to create the cdev nodes for
my drive.

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!
