Linux 5.15 kernel kuburitswa

Mushure memwedzi miviri yebudiriro, Linus Torvalds akapa kuburitswa kweLinux kernel 5.15. Shanduko dzinozivikanwa dzinosanganisira: mutyairi mutsva weNTFS ane rutsigiro rwekunyora, ksmbd module ine SMB server kuisirwa, DAMON subsystem yekuyeuka kuwana yekutarisa, chaiyo-nguva yekuvhara primitives, fs-verity rutsigiro muBtrfs, process_mrelease system yekufona kune nzara yekupindura masisitimu ndangariro, kure certification module. dm-ima.

Iyo itsva vhezheni inosanganisira 13499 inogadzirisa kubva kune 1888 vanogadzira, iyo chigamba saizi i42 MB (shanduko dzakakanganisa 10895 mafaera, 632522 mitsetse yekodhi yakawedzerwa, 299966 mitsetse yakabviswa). Inenge 45% yeshanduko dzese dzakaunzwa mu5.15 dzine hukama nemadhiraivha emidziyo, ingangoita 14% yeshanduko ine chekuita nekuvandudza kodhi yakanangana nehardware architecture, 14% ine hukama netiweki stack, 6% ine hukama nemafaira masisitimu, uye 3% zvine hukama nemukati kernel subsystems.

Zvitsva zvikuru:

  • Disk Subsystem, I/O uye File Systems
    • Iyo kernel yakagamuchira kutsva kwekuita kweNTFS faira system, yakavhurwa neParagon Software. Mutyairi mutsva anogona kushanda mukunyora modhi uye anotsigira ese maficha eiyozvino vhezheni yeNTFS 3.1, kusanganisira yakawedzera faira hunhu, kuwana rondedzero (ACLs), data compression mode, basa rinoshanda rine nzvimbo dzisina chinhu mumafaira (sparse) uye kudzokorora shanduko kubva. iyo log yekudzorera kuvimbika mushure mekukundikana.
    • Iyo Btrfs faira system inotsigira iyo fs-verity mechanism, iyo inoshandiswa kudzora pachena kuvimbika uye kutendeseka kwemafaira ega ega uchishandisa cryptographic hashes kana makiyi ane chekuita nemafaira, akachengetwa munzvimbo yemetadata. Pakutanga, fs-verity yaingowanikwa kune Ext4 uye F2fs faira masisitimu.

      Btrfs inowedzerawo tsigiro yemepu yevashandisi ID yeakakwidzwa faira masisitimu (yaimbotsigirwa neFAT, ext4 uye XFS faira masisitimu). Ichi chimiro chinokutendera kuti uenzanise mafaera emumwe mushandisi pane yakamisikidzwa yekunze chikamu nemumwe mushandisi pane yazvino system.

      Dzimwe shanduko kuBtrfs dzinosanganisira: kukurumidza kuwedzera makiyi kune dhairekitori index kuti uvandudze faira rekugadzira kuita; kugona kushanda raid0 nemudziyo mumwe, uye raid10 nembiri (semuenzaniso, panguva yekugadzirisa zvakare hurongwa); sarudzo "recue=ibadroots" kufuratira muti usiri iwoyo; kukurumidza kwe "kutumira" kushanda; kuderedzwa kwemakakatanwa ekuvhara panguva yekushandurazve mabasa; kugona kushandisa 4K zvikamu pane masisitimu ane 64K ndangariro peji saizi.
