Subject: [PATCH 0/6] Add support of the HBA mode on HP Smart Array P410i controllers

This series of patches adds support of the HBA mode on HP Smart Array P410i RAID controllers.

This is not guaranteed to be correct as I do not have any access to documentation on these controllers. However, this works fine for me on hardware that I have. Also, these changes successfully passes blktests[1] and xfstests[2].

To make sure that this new functionality does not break anything, it is disabled by default and may be enabled only manually using new module parameter.

NAKing this series.
- The P410 controllers do not fully support HBA mode and we do not support adding it to the hpsa driver.
