Right, and we're already running into this problem where some of the function names contain "rdt" and some contain "cat". How about we go with "intel cache alloc"? We avoid the dreaded TLA-fest, it clearly matches up with what's in the Software Developer's Manual (Cache Allocation Technology) and it's pretty simple for people who haven't read the SDM to understand.
