If the patches are accepted, they will be included in Linux kernel 5.6, the release of which is expected in 2-3 months. Compared to the previously added exFAT driver in the kernel, the new driver offers a performance boost of approximately 10%.<\/p>\n<p>De prim\u00e6re forskelle mellem sdfat-driverens version til hoved-Linux-kernen og driveren, der bruges af Samsung i Android:<\/p>\n<ul>\n<li class=\"l\"> Koden til implementeringen af VFAT-filsystemet er blevet fjernet, da dette filsysten allerede underst\u00f8ttes separat i kernen (fs\/fat);\n<li class=\"l\"> Driveren er blevet omd\u00f8bt fra sdfat til exfat;\n<li class=\"l\"> Koden er blevet refaktoreret. Kildekode er blevet tilpasset kravene til kodestil for Linux-kernen;\n<li class=\"l\"> Operationer med metadata s\u00e5som filoprettelse, s\u00f8gning efter filsystemelementer (lookup) og bestemmelse af indholdet af et katalog (readdir) er blevet optimeret.\n<li class=\"l\"> Fejl, som blev opdaget under yderligere test, er blevet rettet.\n<\/ul>\n<p>Vi minder om, at efter at Microsoft <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=51374\">offentliggjorde<\/a><\/noindex> public specifications and provided the opportunity for free use of exFAT patents in Linux, an exFAT driver, also developed at Samsung, was added to the experimental section &#171;staging&#187; (&#171;drivers\/staging\/&#187;) of kernel 5.4, but based on  <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/dorimanx\/exfat-nofuse\">for\u00e6ldet kode<\/a><\/noindex> (version 1.2.9).

Underst\u00f8ttelse af exFAT-filsystemet kom i Windows Vista Service Pack 1 og Windows XP med Service Pack 2. Den maksimale filst\u00f8rrelse blev udvidet fra 4 GB til 16 exabyte sammenlignet med FAT32, derudover blev begr\u00e6nsningen for den maksimale partitionst\u00f8rrelse p\u00e5 32 GB fjernet, for at reducere fragmentering og \u00f8ge hastigheden blev der indf\u00f8rt en bitmap for frie blokke, og begr\u00e6nsningen for antallet af filer i en enkelt mappe blev h\u00e6vet til 65.000, samt blev der givet mulighed for at gemme ACL. <\/p>\n<p><noindex><a rel=\"nofollow\" name=\"link\"><\/a><\/noindex><\/p>\n<p>Kilde: <a \ncontent=\"nofollow\" rel=\"nofollow\"
