Well, I didn't expect it to be really :) At least in my original
announcement about 5.0.0 I did remember to point out it was against 2.0.33
and not likely to work in 2.1.x :)

Actually, this is one of the things that made me want to actually do a
forward port of the code in the near future after the patch stabalizes under
2.0.x. Because of the changes in the 2.1.x scsi mid level code, this entire
section of code that used the referenced function shouldn't need to exist
any longer. Furthermore, there are now some "strange" <grinning widely> new
interrupt semantics under 2.1.80 that I'm going to have to look into and
think about. So, it may still require some changes to fundamental design
issues when considering 2.1.x (including my plans for using the spin locks
instead of cli()/sti() stuff like it does in 2.0.x) But, for my part
anyway, that's still future speak :)
