Als de patches worden aangenomen, zullen ze deel uitmaken van de Linux-kernel 5.6, waarvan de release over 2-3 maanden wordt verwacht. In vergelijking met de eerder aan de kernel toegevoegde exFAT-stuurprogramma, biedt het nieuwe stuurprogramma een prestatieverbetering van ongeveer 10%.<\/p>\n<p>De belangrijkste verschillen tussen de sdfat-stuurprogramma-editie voor de hoofd-Linux-kernel en de stuurprogramma die door Samsung in Android wordt gebruikt:<\/p>\n<ul>\n<li class=\"l\"> De code voor het VFAT-bestandssysteem is verwijderd, aangezien dit bestandssysteem al afzonderlijk wordt ondersteund in de kernel (fs\/fat);\n<li class=\"l\"> De stuurprogramma is hernoemd van sdfat naar exfat;\n<li class=\"l\"> De code is herzien. De bronbestanden zijn aangepast aan de opmaakvereisten voor de Linux-kernel;\n<li class=\"l\"> Optimalisatie van metadata-operaties, zoals het aanmaken van bestanden, zoeken naar FS-elementen (lookup) en het bepalen van de inhoud van een map (readdir), is uitgevoerd.\n<li class=\"l\"> Fouten die tijdens aanvullende tests zijn vastgesteld, zijn gecorrigeerd.\n<\/ul>\n<p>Ter herinnering, nadat Microsoft <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=51374\">heeft gepubliceerd<\/a><\/noindex> publiek beschikbare specificaties en bood de mogelijkheid tot vrij gebruik van patenten op exFAT in Linux, in het experimentele gedeelte &#171;staging&#187; (&#171;drivers\/staging\/&#187;) van kernel 5.4 werd een exFAT-stuurprogramma toegevoegd, ook ontwikkeld in Samsung, maar gebaseerd op  <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/dorimanx\/exfat-nofuse\">verouderde code<\/a><\/noindex> (versie 1.2.9).

De maximale bestandsgrootte werd in vergelijking met FAT32 verhoogd van 4 GB naar 16 exabyte, de beperking voor de maximale partitiegrootte van 32 GB werd opgeheven, een vrijblokbitmap werd ge\u00efntroduceerd om fragmentatie te verminderen en de snelheid te verhogen, de beperking op het aantal bestanden in \u00e9\u00e9n map werd verhoogd tot 65 duizend, en er is een mogelijkheid om ACL
