Cong Wang, zhvillues i n\u00ebn-sistemit t\u00eb menaxhimit t\u00eb trafik\u00ebve (TC, Traffic Control) n\u00eb kernel Linux dhe projektit Multikernel, paraqiti n\u00eb list\u00ebn e zhvilluesve t\u00eb kernelit Linux nj\u00eb sistem t\u00eb ri filesh DAXFS. DAXFS p\u00ebrdor memorin\u00eb RAM p\u00ebr ruajtjen e t\u00eb dh\u00ebnave, funksionon n\u00eb modalitetin vet\u00ebm p\u00ebr lexim dhe ngjason n\u00eb funksionalitet me sistemet e thjeshta t\u00eb filesh ramfs dhe tmpfs.
