Yes sorry. It was on my todo and I never got to it.

OK So actually current osd_initiator code does not use these libraries.
It should, and I have very old code that started on that (hence the comment),
but it was never submitted to Kernel. The OSD protocol calls for all kind of
security levels that use these, but the current code only supports NO_SEC.

I will keep your patch for when security code goes in. Meanwhile I should
at least remove the stale comment.

Thanks
Boaz
