dm: remove dm header from targets

2008-10-21T16:44:59+00:00

Change #include "dm.h" to #include  in all targets.
Targets should not need direct access to internal DM structures.

[PATCH] introduce __blkdev_driver_ioctl()

2008-10-21T11:47:26+00:00

Analog of blkdev_driver_ioctl() with sane arguments.  For
now uses fake struct file, by the end of the series it won't
and blkdev_driver_ioctl() will become a wrapper around it.

dm: linear add merge

2008-07-21T11:00:38+00:00

This patch implements biovec merge function for linear target.

If the underlying device has merge function defined, call it.
If not, keep precomputed value.

[PATCH] dm: map and endio symbolic return codes

2006-12-08T16:29:09+00:00

Update existing targets to use the new symbols for return values from target
map and end_io functions.

There is no effect on behaviour.

Test results:
Done build test without errors.

[PATCH] dm: support ioctls on mapped devices: fix with fake file

2006-10-03T15:04:13+00:00

The new ioctl code passes the wrong file pointer to the underlying device.
No file pointer is available so make a temporary fake one.

ioctl_by_bdev() does set_fs(KERNEL_DS) so it's for ioctls originating
within the kernel and unsuitable here.  We are processing ioctls that
originated in userspace and mapping them to different devices.  Fixing the
existing callers that pass a NULL file struct and consolidating the
fake_file users are separate matters to solve in later patches.

[PATCH] dm: export blkdev_driver_ioctl

2006-10-03T15:04:13+00:00

Export blkdev_driver_ioctl for device-mapper.

If we get as far as the device-mapper ioctl handler, we know the ioctl is not
a standard block layer BLK* one, so we don't need to check for them a second
time and can call blkdev_driver_ioctl() directly.

[PATCH] dm linear: support ioctls

2006-10-03T15:04:13+00:00

When an ioctl is performed on a device with a linear target, simply pass it on
to the underlying block device.

Note that the ioctl will pass through the filtering in blkdev_ioctl() twice.
