It was ported from Bob Pasteur's (of DPT) original + * non-Linux driver.

Consequently, + * a command may take up to 6 minutes to complete after it has been sent + * to the board. + * + * The files dpti_ioctl.h dptsig.h osd_defs.h osd_util.h sys_info.h are part of the + * interface files for Adaptec's management routines. These define the structures used + * in the ioctls. They are written to be portable. They are hard to read, but I need + * to use them 'as is' or I can miss changes in the interface. + * + */ + -- cgit v1.2.3
