Mushure memwedzi miviri yebudiriro, Linus Torvalds kernel release . Pakati pezvinonyanya kuoneka shanduko: Ext4 inoshanda modhi haina-inonzwa, yakaparadzana sisitimu inodaidza kukwirisa faira system, madhiraivha eGPU Mali 4xx/ 6xx/7xx, kugona kubata shanduko ye sysctl kukosha muzvirongwa zveBPF, mudziyo-mapper. module dm-guruva, dziviriro pakurwiswa MDS, tsigiro yeSound Open Firmware yeDSP, optimization yeBFQ kuita, kuunza iyo PSI (Pressure Stall Information) subsystem kune mukana wekushandisa muAndroid.
Iyo vhezheni nyowani inosanganisira gumi nemashanu,15100 zvigadziriso kubva 1882 vanogadzira,
saizi yechigamba - 62 MB (shanduko dzakakanganisa 30889 mafaera, 625094 mitsetse yekodhi yakawedzerwa, 531864 mitsetse yakabviswa). Inenge 45% yezvose zvakaratidzwa mu5.2
shanduko dzine hukama nevatyairi vemidziyo, ingangoita 21% yekuchinja ndeye
mafungiro ekugadzirisa kodhi yakananga kune hardware architectures, 12%
ine chekuita netiweki stack, 3% kune mafaira masisitimu uye 3% kune yemukati
kernel subsystems. 12.4% yeshanduko dzese dzakagadzirwa neIntel, 6.3% neRed Hat, 5.4% neGoogle, 4.0% ne AMD, 3.1% neSUSE, 3% neBMM, 2.7% neHuawei, 2.7% naLinaro, 2.2% neARM , 1.6 % - Oracle.
:
- Disk Subsystem, I/O uye File Systems
- Yakawedzerwa kune Ext4 shanda pasina kusiyanisa nyaya yemavara mumazita emafaira, ayo anoitwa chete ane chekuita nemadhairekitori asina chinhu uchishandisa hunhu hutsva "+F" (EXT4_CASEFOLD_FL). Kana hunhu uhu hwaiswa pane dhairekitori, mashandiro ese ane mafaera uye subdirectories mukati anozoitwa pasina kurangarira nyaya yevatambi, kusanganisira iyo kesi inozofuratirwa pakutsvaga nekuvhura mafaera (semuenzaniso, mafaira Test.txt, test.txt uye test.TXT mumadhairekitori akadaro anozoonekwa akafanana). Nekumisikidza, iyo faira system inoramba iine nyaya-sensitive, kunze kwemadhairekitori ane "chattr +F" hunhu;
- Mabasa ekugadzirisa mavara eUTF-8 mumazita emafaira, ayo anoshandiswa paunenge uchiita tambo yekuenzanisa uye maitiro ekugadzirisa, akabatanidzwa;
- XFS inowedzera zvivakwa zvefaira system yekutarisa hutano uye ioctl nyowani yekubvunza hutano mamiriro. Chinhu chekuyedza chaitwa chekutarisa superblock counters online.
- Yakawedzera new module mudziyo-mapper "", izvo zvinokutendera kuti utevedze kutaridzika kwezvivharo zvakashata pamidhiya kana zvikanganiso paunenge uchiverenga kubva kudhisiki. Iyo module inobvumidza iwe kurerutsa debugging uye kuyedza maapplication uye akasiyana ekuchengetedza masisitimu pamberi pekutadza kutadza;
- Yakakosha kuita optimizations yeBFQ I/O scheduler. Mumamiriro ezvinhu epamusoro I / O mutoro, optimizations yakaitwa Deredza nguva yekushanda sekutanga maapplication kusvika pa80%.
- Yakawedzera nhevedzano yehurongwa hwekufona kwekukwira mafaira masisitimu: , , , , ΠΈ . Aya masisitimu mafoni anotendera iwe kuti ugadzirise zvakasiyana matanho ekumisikidza (gadzirisa iyo superblock, tora ruzivo nezve faira system, kukwira, kubatanidza kune gomo), izvo zvaimboitwa uchishandisa yakajairika mount() system call. Kufona kwakasiyana kunopa kugona kuita zvakanyanya kuomesesa zvimisikidzo uye kuita akaparadzana mashandiro akadai sekugadzirisa zvakare superblock, inogonesa sarudzo, kushandura nzvimbo yekukwira, uye kuenda kune imwe nzvimbo yezita. Mukuwedzera, kushandiswa kwakasiyana kunokubvumira kunyatsoona zvikonzero zvekubuda kwemakodhi ekukanganisa uye kuisa akawanda masosi kune akawanda-layer faira masisitimu, akadai overlayfs;

- Btrfs yakagonesa kuita kweqgroups uye yakavandudza fsync kuuraya kumhanya kwemafaira ane akawanda akaomarara link. Iyo data kutendeseka cheki kodhi yakagadziridzwa, iyo ikozvino inofunga kukuvara kungangodaro kune ruzivo mu RAM isati yatsvaira data ku diski;
- CEPH yakawedzera tsigiro yekutumira mapikicha kuburikidza neNFS;
- Kuitwa kweNFSv4 kukwira mu "soft" modhi yakagadziridzwa (kana kukanganisa kukaitika pakuwana sevha mu "soft" modhi, kufona kwekukurumidza kudzorera kodhi yekukanganisa, uye mu "zvakaoma" modhi yekudzora haina kupihwa kusvika iyo FS. kuvapo kana nguva yekupera kwadzoreredzwa). Kuburitswa kutsva kunopa kwakaringana nguva yekupedza kubata, nekukurumidza kupora kupora, uye nyowani "softerr" yekumisikidza sarudzo inobvumidza iwe kuti uchinje kodhi yekukanganisa (ETIMEDOUT) yakadzoswa kana nguva yekupera yaitika;
- Iyo nfsdcld API, yakagadzirirwa kuronda mamiriro evatengi veNFS, inobvumira sevha yeNFS kuti itarise nemazvo mamiriro emutengi paanotangazve. Saka, iyo nfsdcld daemon ikozvino inogona kuita se nfsdcltrack handler;
- Kune AFS kutevedzera byte range kukiya mumafaira ();
- Virtualization uye Chengetedzo
- Basa rakaitwa kubvisa nzvimbo mu kernel inobvumira kuurayiwa kwekodhi kubva munzvimbo dzinonyorwa dzinoratidza ndangariro, izvo zvinobvumira kuvhara maburi anogona kushandiswa panguva yekurwiswa;
- Iyo nyowani kernel command line parameter "mitigations = "yakawedzerwa, ichipa nzira yakapfava yekudzora kugoneswa kwemamwe matekiniki ekudzivirira kubva panjodzi ine chekuita nekufungidzira kuurayiwa kwemirairo paCPU. Kupfuura "mitigations=off" kunodzima nzira dzese dziripo, uye iyo default mode "mitigations=auto" inogonesa dziviriro asi haikanganisi kushandiswa kweHyper Threading. Iyo "mitigations=auto,nosmt" modhi inodzima Hyper Threading kana ichidikanwa nenzira yekudzivirira.

- Mureza weCLONE_PIDFD wawedzerwa kune clone() system call, kana yatsanangurwa, faira retsananguro "pidfd" rinozivikanwa nemaitiro emwana akagadzirwa rinodzoserwa kumaitiro emubereki. Iyi faira descriptor, semuenzaniso, inogona kushandiswa kutumira masaini pasina kutya kumhanya munhangemutange mamiriro (pakarepo mushure mekutumira chiratidzo, iyo inotarirwa PID inogona kusunungurwa nekuda kwekugadziriswa kwekugadzirisa uye kugarwa neimwe nzira);
- Yechipiri vhezheni yezvikwata, iyo yefreezer controller mashandiro akawedzerwa, iyo iwe yaunogona kumisa basa muboka uye kwenguva pfupi kusunungura zvimwe zviwanikwa (CPU, I / O, uye ingangoita ndangariro) kuita mamwe mabasa. Kutungamira kunoitwa kuburikidza ne cgroup.freeze uye cgroup.events control mafaera mumuti weboka. Kupinda 1 mu cgroup.freeze inoomesa maitiro muboka razvino uye mapoka ese evana. Sezvo kutonhora kuchitora nguva, imwe cgroup.events faira inopiwa kuburikidza iyo iwe unogona kuziva pamusoro pekupedzwa kwekushanda;
- kunze kweiyo ndangariro hunhu hwakasungirirwa kune imwe neimwe node mu sysfs, iyo inokutendera iwe kuti uone kubva munzvimbo yemushandisi chimiro chekugadzirisa ndangariro mabhangi mumasisitimu ane heterogeneous memory;
- Iyo PSI (Pressure Stall Information) subsystem yakagadziridzwa, iyo inokutendera kuti uongorore ruzivo nezve nguva yekumirira yekugamuchira akasiyana zviwanikwa (CPU, ndangariro, I / O) kune mamwe mabasa kana seti yemaitiro muboka. Uchishandisa PSI, vashandisi venzvimbo yevashandisi vanogona kunyatso fungidzira mwero wehurongwa hwekutakura uye kuderera mapatani kana ichienzaniswa neAvhareji Yemutoro. Iyo vhezheni nyowani inopa rutsigiro rwekumisikidza senitivity zvikumbaridzo uye kugona kushandisa iyo poll() kufona kuti ugamuchire chiziviso chekuti kuseta zvikumbaridzo zvakakonzereswa kweimwe nguva yenguva. Iyi ficha inobvumira Android kutarisa kushomeka kwendangariro padanho rekutanga, kuona kwainobva matambudziko uye kumisa zvisina kukosha maapplication pasina kukonzera matambudziko anoonekwa kumushandisi. Kana kuyedzwa kwekushushikana, PSI-yakavakirwa ndangariro kushandiswa kwekutarisa maturusi airatidza 10 nguva shoma dzenhema positives zvichienzaniswa nevmpressure statistics;
- Iyo kodhi yekutarisa zvirongwa zveBPF yakagadziridzwa, iyo inobvumira kutarisa kusvika ku20 nguva nekukurumidza kune makuru mapurogiramu. Optimization yakaita kuti zvikwanise kusimudza muganho pahukuru hwezvirongwa zveBPF kubva pa4096 kusvika kune miriyoni mirairo;
