mpii specs do not use terms write-back or write-through, they rather talk about write cache being enabled or disabled. they obviously mean write-back cache. i believe for the bioctl user it's more important to know if actual writes are deferred or not, so i would rather say "Write Cache Enabled/Disabled" or "Write Cache On/Off" or something similar rather then if it's WB or WT. oterwise people will have to look in the man page for what WB or WT stands for and then search wikipedia for what does it mean.. just my 2 cents.
