Staging: hv: storvsc: Fix a bug in create_bounce_buffer()

2011-12-08T22:59:47+00:00

Set the length field of the scatter gather elements correctly when we create
the bounce buffer. When we use the bounce buffer for a "write" operation,
the act of copying to the bounce buffer, correctly deals with this issue.
However, on the "read" side, the current code was not correctly setting
the buffer length. Fix this bug. Note that when we copy from the bounce
buffer (for the read case), the amount we copy is controlled by the original
scatter gather list given to the driver.

This removes the hv_mouse driver as it's now in Jiri's HID tree in the
"proper" place.

Staging: hv: storvsc: Implement per device memory pools

2011-12-01T18:27:00+00:00

The current code implemented a per-HBA memory pool mechanism. For IDE disks
managed by this driver, there is a one to one correspondance between the
block device and the associated virtual HBA and since currently only IDE devices
can be the boot device, this addressed the deadlock issues that were raised during
the review process. This patch implements a per-lun memory pool mechanism.

Staging: hv: storvsc: Cleanup storvsc_device_alloc()

2011-12-01T18:26:59+00:00

The code in storvsc_device_alloc() is not needed as this would be
done by default. Get rid of it. We still keep the function as we use
this hook to allocate per-LUN memory pools in a later patch.

Staging: hv: storvsc: Disable clustering

2011-12-01T18:26:59+00:00

Disable clustering, since the host side on Hyper-V requires that
each I/O element not exceed the page size. As part of this
cleanup, get rid of the function to merge bvecs, as the primary
reason for this function was to avoid having an element exceed
the page size.

We need to properly add the hid device to correctly initialize the
sysfs state. While this patch is against the staging tree; Jiri,
please pick up this patch as you merge the Hyper-V mouse driver.
