Hi Jens,
Another tiny patch.
Removed __packed before the struct smart_attr and added __packed at end of
the structure to fix padding issue.

On module load, creates a debugfs parent 'rssd' in debugfs root. Then for each
device, create a new node with corresponding disk name. Under the new node, two
entries 'registers' and 'flags' are created.
NOTE: These entries were removed from sysfs in the previous patch

* If a ncq command time out and a non-ncq command is active, skip restart port
* Queue(pause) ncq commands during operations spanning more than one non-ncq commands - secure erase, download microcode
* When a non-ncq command is active, allow incoming non-ncq commands to wait instead of failing back
* Changed timeout for download microcode and smart commands
* If the device in write protect mode, fail all writes (do not send to device)
* Set maximum retries to 2

Earlier, rebuild monitoring was done in the context of probe. Now the service
thread takes the responsibility of rebuild monitoring, and probe returns good
status.

Kill the declarations in the header file and mark them as static.
Reshuffle a few functions to ensure that everything is properly
declared before being used.

to the ioctl handler and subsequently to the exec_drive_taskfile()
function.
