I began on a scsi-mid-layer-api.txt file a few years ago. :( Sadly I haven't touched it since then. You can see if it may help you any: http://www.xenotime.net/linux/doc/scsi-interfaces.txt It's just text from scsi .h and .c files. You can also see if this other *also outdated* SCSI driver doc helps you any: (get pdf or OpenOffice files from http://developer.osdl.org/dev/opendrivers/wiki/index.php/Storage ) Feel free to update/correct either of them. :) --- ~Randy - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
