[PATCH 00/15] Add struct to pass in optional args to scsi_execute

[Mike Christie <michael.christie@xxxxxxxxxx>]

The following patches made over Martin's 6.1 scsi queue branch adds a
struct that contains optinal arguments to the scsi_execute* functions.
Right now, it's just a nice cleanup, but will be needed for the patches
that allow the scsi passthrough users to control retries. I separated
the 2 sets to make it easier to review and post.
