It was ported from Bob Pasteur's (of DPT) original30non-Linux driver.

Consequently,86a command may take up to 6 minutes to complete after it has been sent87to the board.88 89The files dpti_ioctl.h dptsig.h osd_defs.h osd_util.h sys_info.h are part of the90interface files for Adaptec's management routines. These define the structures used91in the ioctls. They are written to be portable. They are hard to read, but I need92to use them 'as is' or I can miss changes in the interface.93
