Ukukhutshwa kwe-kernel ye-Linux 5.15

Emva kweenyanga ezimbini zophuhliso, uLinus Torvalds ubonise ukukhululwa kweLinux kernel 5.15. Utshintsho oluphawulekayo lubandakanya: umqhubi omtsha we-NTFS ngenkxaso yokubhala, imodyuli ye-ksmbd kunye nokuphunyezwa kweseva ye-SMB, inkqubo ephantsi ye-DAMON yokuqwalasela ukufikelela kwimemori, i-real-time locking primitives, inkxaso ye-fs-verity kwi-Btrfs, inkqubo_mrelease inkqubo yokufowunela imemori yenkqubo yokuphendula indlala, imodyuli yesiqinisekiso esikude. dm-ima.

Uguqulelo olutsha lubandakanya ukulungiswa kwe-13499 ukusuka kubaphuhlisi be-1888, ubungakanani bepatch yi-42 MB (utshintsho oluchaphazelekayo lweefayile ze-10895, imigca ye-632522 yekhowudi yongezwa, imigca ye-299966 isusiwe). Ngokumalunga ne-45% yazo zonke iinguqu ezifakwe kwi-5.15 zihambelana nabaqhubi besixhobo, malunga ne-14% yeenguqu zihambelana nokuhlaziya ikhowudi ethile kwi-architectures ye-hardware, i-14% inxulumene ne-stack networking stack, i-6% inxulumene neenkqubo zefayile, kunye ne-3% zinxulumene ne-kernel yangaphakathi kwiindlela ezisezantsi.

Iinguqulelo eziphambili:

• Inkqubo engaphantsi kweDisk, I/O kunye neeNkqubo zeFayile
  • I-kernel yamkele ukuphunyezwa okutsha kwenkqubo yefayile ye-NTFS, evulwe yiParagon Software. Umqhubi omtsha unokusebenza kwimodi yokubhala kwaye uxhasa zonke iimpawu zenguqu yangoku ye-NTFS 3.1, kubandakanywa iimpawu zefayile ezandisiweyo, uluhlu lokufikelela (ACLs), imodi yoxinzelelo lwedatha, umsebenzi osebenzayo kunye nezikhala ezingenanto kwiifayile (sparse) kunye nokuphinda utshintshe utshintsho oluvela ilog yokubuyisela ingqibelelo emva kokusilela .
  • Inkqubo yefayile ye-Btrfs ixhasa i-fs-verrity mechanism, esetyenziselwa ukulawula ngokuphandle ukunyaniseka kunye nokunyaniseka kweefayile ezizimeleyo zisebenzisa i-cryptographic hashes okanye izitshixo ezinxulumene neefayile, ezigcinwe kwindawo yemetadata. Ngaphambili, i-fs-verrity ibifumaneka kuphela kwiinkqubo zefayile ze-Ext4 kunye ne-F2fs.

  • Inketho ye-lowlatency yongezwe kumqhubi we-usb-audio ukulawula ukufakwa komsebenzi kwimowudi encinci ye-latency. Kongezwe i-quirk_flags ukhetho lokudlula useto lwesixhobo esithile.

Kwangelo xesha, iLatin American Free Software Foundation yenze inguqulelo ye-kernel yasimahla 5.15-Linux-libre 5.15-gnu, ecinyiweyo kwizinto ze-firmware kunye nabaqhubi abaqulathe amacandelo angasimahla okanye amacandelo ekhowudi, umda wawo ulinganiselwe. ngumvelisi. Ukukhutshwa okutsha kusebenzisa imveliso yomyalezo kwilogi malunga nokugqitywa kokucoca. Iingxaki zokuvelisa iipakethi usebenzisa i-mkspec zilungisiwe, inkxaso yeepakethe ze-snap iphuculwe. Isuse ezinye izilumkiso ezibonisiweyo xa kusenziwa ifayile yeheader ye-firmware.h. Kuvunyelwe imveliso yolunye uhlobo lwezilumkiso (“ifomati-ezongezelelweyo-args”, izimvo, imisebenzi engasetyenziswanga kunye neziguquguqukayo) xa kusakhiwa ngendlela ethi “-Werror”. Ukucoca umqhubi we-gehc-achc. Ikhowudi yokucoca i-blob ehlaziyiweyo kubaqhubi kunye ne-subsystems adreno, i-btusb, i-btintel, i-brcmfmac, i-aarch64 qcom. Ukucocwa kwabaqhubi i-prism54 (isusiwe) kunye ne-rtl8188eu (ifakwe endaweni ye-r8188eu) kumisiwe.
