Hi everybody,
These series of patches adds support for io-shipping feature in LSI external storage.
This feature provides access to any given LUN via both storage processors as active
but only one of these storage processors owns the LUN. The storage processor which
owns the lun, provides the best performance. The storage processor which does not own
the lun, uses the indirect communication to owning processor.
