From: "Ewan D. Milne"
Added support for additional scsi_device events in sysfs, as
well as support for scsi_target events. Also added "rescan"
node in scsi_target sysfs to permit targets to be rescanned
from udev rules in a more straightforward way.

Avoid duplicate tests when examining sense data for FM/EOM/ILI
bits. Moved extraction of status to scsi_normalize_sense() if
the config option CONFIG_SCSI_ENHANCED_UA is used, because
descriptor format sense data is already being parsed there.

The names of the struct and some of the functions for scsi_device
events are too generic and do not match the comments in the source.
Changed all of the names to begin with sdev_ in order to avoid
naming issues and confusion with scsi_target events to be added.

"buf" is 128 characters and "vpd->device_identifier" is 256. It makes
the static checkers complain.

Probably we should just raise VPD_TMP_BUF_SIZE to 300.
