K\u00e4sitades j\u00e4rgmise paranduste partii k\u00fcsimusi, mis on ette n\u00e4htud kaasamiseks tuuma 6.11-rc5, kirjutas Linus Torvalds, et hakkab kahetsema, et v\u00f5ttis Bcachefs-failis\u00fcsteemi tuuma. Torvalds oli rahulolematu, kuna Bcachefsi autor Kent Overstreet saadab liiga mahukaid parandusi, mis mitte ainult ei paranda vigu, vaid j\u00e4tkavad ka funktsionaalsuse arendamist, kuigi funktsionaalsed muudatused on lubatud ainult uue versiooni arendamise algusetapis, ja rc5 etapil v\u00f5etakse vastu ainult eraldi v\u00e4ikesed parandused, mille suurus ei tohiks \u00fcldiselt \u00fcletada 100 rida koodi. <\/p>\n

Bcachefs'i jaoks saadetud patch, milles lisati 1309 rida ja eemaldati 671 rida 39 failist, lisaks vigade parandamisele sisaldas kaht olulist muudatust: uue andmestruktuuri toetamist, et hallata vabu elemente m\u00e4lus ja v\u00f5imalust teisendada hash-tabele m\u00e4lus. Uus struktuur lisati, et v\u00e4ltida liigseid m\u00e4lulukke ja v\u00e4ltida olukordi, mis v\u00f5ivad p\u00f5hjustada sulgemise konflikte mitme l\u00f5ime koormate korral. <\/p>\n

See ei ole esimene kord, kui suured parandused Bcachefs'i jaoks saadetakse p\u00e4rast muudatuste vastuv\u00f5tu akent, ja see ei ole esimene kord, kui lihtsamate vigade paranduste asemel edendatakse keerukamaid funktsionaalseid t\u00e4iustusi, mida esitatakse paranduste tegemise taotlustena uue arendusfiliaali l\u00f5ppfaasides. Linus Torvalds vastas saadetud pull-p\u00e4ringule: <\/p>\n

Ega, viimane pull-request oli samuti ulatuslik. See pull-request on samuti liiga mahukas, k\u00e4sitledes teemasid, mis ei ole seotud Bcachefs-iga, ja ei esinda isegi kaugelt mingit regressiooni. Teatud hetkel muutub \"k\u00f5ige parandamine\" lihtsalt arenduseks, ja see on see hetk. Keegi normaalne inimene ei kasuta Bcachefs-i ja ei oota sellelt stabiilsust, seega iga kasutaja on eksperimentide valdkond. Bcachefs-i plaastrid on muutunud omamoodi \"suurks arenduseks vabastamisprotsessi k\u00e4igus, mitte enne seda\", nii kaugele, et hakkasin Bcachefs-i valiku \u00fcle kahetsema. Kui Bcachefs ei suuda normaalselt t\u00f6\u00f6tada p\u00f5hij\u00f5udude arendusgraafiku j\u00e4rgi, siis v\u00f5ib-olla ei peaks see olema p\u00f5hij\u00f5udude koosseisus. See on juba naeruv\u00e4\u00e4rsusest kaugemale l\u00e4inud. <\/p><\/blockquote>\n

Kent Overstreet vastas, et Bcachefs on kindlasti usaldusv\u00e4\u00e4rsem kui Btrfs ja ta t\u00f6\u00f6tab selle nimel, et muuta see veelgi vastupidavamaks ja usaldusv\u00e4\u00e4rsemaks kui XFS ja EXT4, rakendades l\u00f5pp-punkti andmete terviklikkuse mehhanismi. Kent r\u00f5hutas ka, et soovitatud muutused on otseselt seotud usaldusv\u00e4\u00e4rsuse parandamisega, ja kui viga teistes tuumaprotsektorites v\u00f5ib piiruda s\u00fcsteemi j\u00e4\u00e4nud ja taask\u00e4ivitamisega, siis failis\u00fcsteemides on vea hind v\u00e4ga k\u00f5rge ja see v\u00f5ib p\u00f5hjustada varjatud andmekahjustusi, mida m\u00e4rgatakse alles n\u00e4dalate p\u00e4rast. <\/p>\n

Torvalds vaidles vastu, et suurte Linuxi jaotuste seas ei ole endiselt \u00fchtegi, mis kasutaks Bcachefs, ning juhtis t\u00e4helepanu, et tuleb j\u00e4rgida Linuxi tuumade versiooni v\u00e4ljaandmise reegleid, kuna selliste suurte plaastritega, mis sisaldavad \u00fcle 1000 koodi rea, on uute vigade tekkimise v\u00f5imalus. Praegu pole Bcachefsi soovitatud parandused Linuxi tuuma vastu v\u00f5etud ja Bcachefsi arendaja pole veel valmistanud ajakohastatud pull-kutsu, mis vabastab uue funktsionaalsuse lisamisest ja keskendub ainult vigade parandamisele.
