Samsung yakurudzira imwe exFAT mutyairi sarudzo yeLinux kernel

Samsung suggested yekuisirwa muLinux kernel, seti yezvigamba nekushandiswa kwemutyairi mutsva weexFAT, zvichibva pane yazvino "sdfat" kodhi base, yakagadziridzwa firmware yeSamsung Android smartphones. Kana mapeche akagamuchirwa, anozoverengerwa muLinux 5.6 kernel, inotarisirwa kuburitswa mumwedzi 2-3. Kuenzaniswa nemutyairi weexFAT akambowedzerwa kune kernel, mutyairi mutsva anopa kuwedzera kwekuita kweanenge gumi%.

Misiyano mikuru pakati peiyo sdfat mutyairi weLinux kernel uye mutyairi anoshandiswa neSamsung mu Android:

• Iyo kodhi nekushandiswa kweiyo VFAT faira system yakabviswa, sezvo iyi faira system yatove inotsigirwa zvakasiyana mukernel (fs/fat);
• Mutyairi akatumidzwa zita kubva sdfat kusvika exfat;
• Kodhi yakadzokororwa. Iwo manyoro manyoro anogadziridzwa kune zvinodikanwa zvekodha fomati yeLinux kernel;
• Mashandiro ane metadata akagadziridzwa, sekugadzira mafaera, kutsvaga faira system zvinhu (kutarisa) uye kuona zvirimo mudhairekitori (readdir).
• Zvikanganiso zvakaonekwa panguva yekuwedzera kuyedzwa zvakagadziriswa.

Ngatikuyeuchidzei kuti mushure meMicrosoft yakabudiswa ruzhinji rwevanhu uye kugonesa kushandiswa kwemahara kwemahara eexFAT patents paLinux, mutyairi weexFAT, akagadziridzwawo neSamsung asi zvichibva pa. legacy code (shanduro 1.2.9). Android firmware vanofarira vaive ported mutyairi mutsva sdFAT (2.x), asi Samsung yakazvimiririra yakafunga kusimudzira mutyairi uyu muLinux kernel. Mukuwedzera, Paragon Software yakavhurwa mumwe mutyairi, yakambopihwa mune imwe seti yevatyairi.

Iyo exFAT faira sisitimu yakagadzirwa neMicrosoft kukunda zvipimo zveFAT32 kana ichishandiswa pane yakakura-inotakura Flash drive. Tsigiro yeiyo exFAT faira system yakaonekwa muWindows Vista Service Pack 1 uye Windows XP ine Service Pack 2. Iyo yakakura faira saizi yakaenzaniswa neFAT32 yakawedzerwa kubva ku4 GB kusvika ku16 exabytes, uye kuganhurirwa kwehukuru hwekuparadzanisa saizi ye32 GB yakabviswa. , kuderedza kupatsanurwa uye kuwedzera kukurumidza, bitmap yezvivharo zvakasununguka yakaunzwa, muganho wenhamba yemafaira mune imwe dhairekitori yakasimudzwa kusvika 65 zviuru, uye kugona kuchengetedza ACLs kwakapihwa.
