There is no such thing as "ascii" for case sensitivity. The case and
ordering rules are locale not symbol set based and they also depend
totally on the exact semantics of whatever legacy technology you are
interfacing with. I assume you mean "C locale, ascii character set",
which limits your debugger to speaking a subset of American English (no
café or naïve 8))
Any routine of that nature belongs in the user environment to which it
applies, and should be used with care, and preferably pushed to user
space or to a user app on the debug hosting box as kgdb does.
The only general, usable strnicmp safe for general kernel use would be a
full all singing all dancing UTF-8 symbol aware arbitary locale
implementation. And that we *definitely* do not want in kernel.
