[SCSI] vmw_pvscsi: Some improvements in pvscsi driver.

2014-03-19T22:04:46+00:00

This change is about the following:
(1) If the number of targets is 16+ then default ring_pages to 32.
(2) Change default queue depth (per device) to 254.
(3) Implement change_queue_depth function so that queue_depth per device can
    be changed at run time. Honors the request only if coming from sysfs.
(4) Clean up the info returned by modinfo.

[SCSI] vmw_pvscsi: Fix pvscsi_abort() function.

2014-03-19T22:04:45+00:00

This change ensures that pvscsi_abort() function returns SUCCESS
only when the command in question was actually completed, otherwise
returns FAILURE. The code before change, was causing a bug where
driver tries to complete a command to the mid-layer while the mid-layer
has already requested the driver to abort that command, in response
to which the driver has responded with SUCCESS causing mid-layer
to free the command struct.

Fetch the config page from the device to learn max target id to set
host->max_id.

Also, fix some indentation issues and update the 'Maintained by' field.
