Tomo hi.
This driver has a patch in scsi-pending that removes exactly all
this code. And converts it to the new scsi_error API.
You have caught me in the middle of sweeping the entire tree,
converting all these drivers, to code like the patch
to fas216.c. This is exactly what is needed to satisfy
the condition you stated, "is needed for farther cleanup".
(Though I admit this was done on a low priority, as I'm
busy with other stuff)
James
It is about time for this patch, it has even been
acknowledged by a maintainer. Also the second patch to
arm is do.
