Alternatively, what about a flag that says "if you use this flag, the size should be left-shifted by X bits before processing"? That allows you to do TRIM or WRITE_ZEROES on much larger chunks, without being limited to "whole disk" commands. We should probably make it an illegal flag for any command that actually sends data over the wire, though. -- < ron> I mean, the main *practical* problem with C++, is there's like a dozen people in the world who think they really understand all of its rules, and pretty much all of them are just lying to themselves too. -- #debian-devel, OFTC, 2016-02-12
