One or two words would do the trick. If this is universally understood, however, then disregard this message.This was originally /* if (qemuCaps->version < 3000000) */ to basically add something that has the same format as explicit version checks and thus is easily greppable. Unfortunately our not-very-clever syntax check moaned that the formatting of 'if' isn't compliant thus I've removed the if.
=D sorry, can't stop grinning =)
The idea is to have something which references 'qemuCaps->version' and thus is the same as other version checks.
I get it, I meant something like "not needed after qemuCaps->..." or "remove for (qemuCaps->...", but it's fine, it's just me overthinking comments. The idea will be clearly visible when someone git-blames the line, so it's fine.
