Ho hlahisitsoe mofuta o mocha oa mokhanni oa exFAT bakeng sa Linux kernel

Moqapi oa Korea Park Ju Hyung, ea sebetsanang le ho tsamaisa firmware ea Android bakeng sa lisebelisoa tse fapaneng, tsebisoa khatiso e ncha ea mokhanni bakeng sa sistimi ea faele ea exFAT - exfat-linux, e leng fereko e tsoang ho mokhanni oa "sdFAT", ntlafala ka Samsung. Hajoale, lekala la sethala la Linux kernel le se le ntse le le teng eketsa Mokhanni oa exFAT oa Samsung, empa o thehiloe ho codebase lekala la khale la mokhanni (1.2.9). Hajoale, Samsung e sebelisa mofuta o fapaneng ka ho felletseng oa mokhanni oa "sdFAT" (2.2.0) ho li-smartphones tsa eona, lekala la eona e neng e le nts'etsopele ea Park Ju Hyung.
