Pat\u0161od lisavad ka UTF-8 s\u00fcmbolite toe faili nimedes.<\/p>\n

T\u00e4htede suure\/v\u00e4ikese registreerimise re\u017eiim saab valikuliselt aktiveerida eraldi kataloogide k\u00fclge uue atribuudi '+F' (EXT4_CASEFOLD_FL) kaudu. Kui see atribuut on seadistatud kataloogile, siis k\u00f5ik failide ja alamkataloogide toimingud toimuvad t\u00e4htede registreerimist ignoreerides, sealhulgas ignoreeritakse suure ja v\u00e4ikese t\u00e4he erinevust failide otsimise ja avamise toimingutes (n\u00e4iteks, failid Test.txt, test.txt ja test.TXT sellistes kataloogides peetakse samav\u00e4\u00e4rseks). Vaikimisi, v\u00e4lja arvatud kataloogid, millel on atribuut '+F', j\u00e4tkab failis\u00fcsteem registreerimise suhtes tundlikkust. Registreerimistegevuse aktiviseerimiseks on ette n\u00e4htud muudetud utiliidid, e2fsprogs<\/a><\/noindex>.<\/p>\n

Pat\u0161od on ette valmistanud Gabriel Krisman Bertazi, firma Collabora t\u00f6\u00f6taja, ja need on vastu v\u00f5etud seitsmenda<\/a><\/noindex> katse j\u00e4rel p\u00e4rast kolme aasta<\/a><\/noindex> arendamiseks ja t\u00e4iendamiseks. Rakendus ei muuda salvestusvormingut ja t\u00f6\u00f6tab ainult nimesildide v\u00f5rdlemise loogika muutmise tasemel funktsioonis ext4_lookup() ja hash'i asendamisel dcache (Directory Name Lookup Cache) struktuuris. Atribuudi '+F' v\u00e4\u00e4rtus salvestatakse \u00fcksikute kataloogide inode'ides ja laiendab see k\u00f5ikidele alamfailidele ja -kataloogidele. Teave kodeeringu kohta salvestatakse superplokki.<\/p>\n

Kuna nimekolisioonide v\u00e4ltimiseks saab atribuut '+F' seadistada ainult t\u00fchjadesse kataloogidesse failis\u00fcsteemides, kus mountimise ajal on lubatud Unicode'i tugi failide ja kataloogide nimedes. Kataloogielementide nimed, millel on aktiveeritud atribuut '+F', muudetakse automaatselt v\u00e4ikeste t\u00e4htedega ja peegelduvad selliselt dcache'is, kuid hoitakse kettal algselt m\u00e4\u00e4ratud kujul, st, vaatamata nimede t\u00f6\u00f6tlemisele registreerimise suhtes, n\u00e4idatakse ja salvestatakse nimed ilma t\u00e4htede registreerimise teabe kadumiseta (kuid s\u00fcsteem ei luba luua failinime samade s\u00fcmbolitega teises registreeringus).<\/p>\n
