Kutulutsidwa kwa kernel ya Linux 5.15

Pambuyo pa miyezi iwiri yachitukuko, Linus Torvalds adapereka kutulutsidwa kwa Linux kernel 5.15. Zosintha zodziwika bwino zikuphatikiza: dalaivala watsopano wa NTFS wokhala ndi chithandizo cholembera, gawo la ksmbd lokhazikitsa seva ya SMB, DAMON subsystem yowunikira kukumbukira, zoyambira zenizeni zotsekera, thandizo la fs-verity ku Btrfs, process_mrelease system kuyitanira kukumbukira kwamayankho a njala, gawo lachiphaso chakutali. dm-ima.

Mtundu watsopanowu umaphatikizapo kukonza kwa 13499 kuchokera kwa opanga 1888, kukula kwa chigamba ndi 42 MB (zosintha zomwe zidakhudza mafayilo 10895, mizere ya 632522 yamakhodi idawonjezedwa, mizere 299966 idachotsedwa). Pafupifupi 45% ya zosintha zonse zomwe zidayambitsidwa mu 5.15 zimagwirizana ndi madalaivala a zida, pafupifupi 14% ya zosintha zimagwirizana ndi kukonzanso kachidindo kamangidwe ka ma hardware, 14% ikugwirizana ndi stack networking, 6% ikugwirizana ndi mafayilo amafayilo, ndi 3% zimagwirizana ndi ma kernel subsystems amkati.

Zatsopano zazikulu:

• Disk Subsystem, I/O ndi File Systems
  • Kernel yatengera kukhazikitsa kwatsopano kwa fayilo ya NTFS, yotsegulidwa ndi Paragon Software. Dalaivala watsopano amatha kugwira ntchito polemba ndikuthandizira mawonekedwe onse amtundu waposachedwa wa NTFS 3.1, kuphatikiza mawonekedwe amafayilo owonjezera, mindandanda yofikira (ACLs), njira yophatikizira deta, ntchito yabwino yokhala ndi malo opanda kanthu m'mafayilo (sparse) ndikusinthanso kusintha kuchokera ku chipika chobwezeretsa kukhulupirika pambuyo polephera.
  • Dongosolo la mafayilo a Btrfs limathandizira njira ya fs-verity, yomwe imagwiritsidwa ntchito poyang'anira kukhulupirika ndi kutsimikizika kwa mafayilo amtundu uliwonse pogwiritsa ntchito ma cryptographic hashes kapena makiyi ogwirizana ndi mafayilo, osungidwa m'dera la metadata. M'mbuyomu, fs-verity inali kupezeka pamafayilo a Ext4 ndi F2fs okha.

    Btrfs imawonjezeranso kuthandizira pakujambula ma ID a ogwiritsa ntchito pamafayilo okwera (omwe kale anali othandizira FAT, ext4 ndi XFS mafayilo). Izi zimakulolani kuti mufananize mafayilo a wogwiritsa ntchito wina pagawo lakunja lokhazikitsidwa ndi wina wogwiritsa ntchito pakali pano.

    Zosintha zina ku Btrfs zikuphatikiza: kuwonjezera mwachangu makiyi ku index index kuti athandizire kupanga mafayilo; Kutha kugwira ntchito raid0 ndi chipangizo chimodzi, ndi raid10 ndi ziwiri (mwachitsanzo, panthawi yokonzanso gululo); kusankha “rescue=ibadroots” kunyalanyaza mtengo wolakwika; kufulumizitsa ntchito ya "kutumiza"; kuchepetsa mikangano yotsekera pakusinthanso ntchito; kuthekera kogwiritsa ntchito magawo a 4K pamakina okhala ndi kukula kwa tsamba la 64K.

  • Mu XFS, kuthekera kogwiritsa ntchito masiku pambuyo pa 2038 mu fayilo yamafayilo kwakhazikika. Inakhazikitsa njira yochepetsera kutsekedwa kwa inode ndikuthandizira kuchedwa kuyika ndi kuchotsa mawonekedwe a fayilo. Kuti muchepetse zovuta, kuthekera koletsa magawo a disk kwa magawo omwe adayikidwa kale kwachotsedwa (mutha kuletsa mwamphamvu ma quotas, koma kuwerengera komwe kumalumikizidwa nawo kumapitilira, chifukwa chake kukonzanso kumafunika kuti muwalepheretse).
