Yeah. Me too. Apparently I fail at English. Basically this allows new vifs to be assigned to a chanctx as long as chanctx's reservation chandefs *and* chanctx's current chandef (implied by assigned vifs, if any) *and* the new vif chandef are compatible. chanctx being used for in-place reservation with conflicting channels are skipped. This also it makes it possible to assign a vif to a chanctx that has been created for reservation only (that hasn't been finalized yet) and has no vifs assigned whatsoever. Michał
