Arutledes, mis k\u00e4sitlevad uut partiid parandustest, mida on ette n\u00e4htud kernelisse 6.11-rc5, kirjutas Bcachefsi autor Linus Torvalds, et ta hakkab kahetsema, et v\u00f5ttis Bcachefsi failis\u00fcsteemi kernelisse. Torvalds'i rahulolematus tuleneb sellest, et Kent Overstreet, Bcachefsi autor, saadab liiga mahukaid parandusi finaalkandidaatide v\u00e4ljaandmisetapis, mis mitte ainult ei paranda vigu, vaid j\u00e4tkab funktsionaalsuse arendamist, kuigi funktsionaalsed muutused on lubatud ainult uue haru arendamise algfaasis ning rc5-etapis v\u00f5etakse vastu ainult eraldi v\u00e4ikseid parandusi, mille suurus ei tohiks soovituslikult \u00fcletada 100 koodirida. <\/p>\n

Bcachefsile saadetud plaastrites, kus lisati 1309 rida ja eemaldati 671 rida 39 failist, sisaldasid lisaks vigade parandamisele ka kaks olulist muudatust: toe uuele andmestruktuurile vabade elementide nimekirja haldamiseks vahemikus ja v\u00f5imaluse vahetada rippmen\u00fc\u00fc tabelid vahemikus. Uus struktuur lisati, et vabaneda liigsetest vahem\u00e4lu lukustustest ja v\u00e4listada olukorrad, mis v\u00f5ivad p\u00f5hjustada lukustuste konflikte mitme l\u00f5ime koormuste ajal. <\/p>\n

See ei ole esimene juhtum, kui suured parandused Bcachefsi jaoks saadetakse p\u00e4rast muudatuste vastuv\u00f5tu akent, ja see ei ole esimene juhtum, kui lihtsate vigade paranduste asemel edendatakse raskemaid funktsionaalseid lisandusi, mis tehakse l\u00f5ppfaasis h\u00fcvitamise taotlustega. Linus Torvalds vastas saadetud pull-requestile: <\/p>\n

\u201ePiisavalt. Viimane pull-p\u00e4ring oli samuti suur. See pull-p\u00e4ring on samuti liiga mahukas, k\u00e4sitleb asju, mis ei puuduta Bcachefs ja ei ole isegi kaugelt mingi regressioon. \u00dchel hetkel muutub \u201emidagi parandamine\u201c lihtsalt arenduseks, ja see on just see hetk. Keegi, kellel on terve m\u00f5istus, ei kasuta Bcachefs'i ega oota sellelt stabiilsust, seega iga kasutaja \u2014 see on katsetuste ala. Bcachefs'i plaastrid on muutunud omamoodi \u201esuureks arenduseks v\u00e4ljaku kuup\u00e4eva ettevalmistamise ts\u00fckli ajal, mitte enne seda\u201c, nii palju, et hakkan kahetsema Bcachefs'i v\u00f5tmist. Kui Bcachefs ei suuda korralikult t\u00f6\u00f6tada vastavalt peamise (upstream) kerneli arenduskava j\u00e4rgi, siis ei tohiks see olla peases kernelis. See on juba naljast 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 tugevamaks ja usaldusv\u00e4\u00e4rsemaks kui XFS ja EXT4, kasutades andmete terviklikkuse mehhanismi (end to end data Integrity). Kent r\u00f5hutas ka, et ettepanekud on otseselt seotud usaldusv\u00e4\u00e4rsuse t\u00f5stmisega ning kui vigade korral muudes kernelis\u00fcsteemides on t\u00f5en\u00e4oliselt piiratud krahhide ja taask\u00e4ivitustega, siis failis\u00fcsteemides on vea hind v\u00e4ga k\u00f5rge ja see v\u00f5ib viia varjatud andmekahjustuseni, mida v\u00f5ib m\u00e4rgata alles n\u00e4dalate p\u00e4rast. <\/p>\n

Torvalds v\u00e4itis, et suured Linuxi distributsioonid, mis kasutavad Bcachefs'i, puuduvad endiselt ning r\u00f5hutas, et tuleb j\u00e4rgida Linuxi tuumarelease arendamise reegleid, kuna on oht, et selliste suurte plaastrite t\u00f5ttu, mis sisaldavad rohkem kui 1000 koodirida, v\u00f5ivad tekkida uued vead. Praegu ei ole Bcachefs'i kohta arutatavad parandused saanud Linuxi tuumasse, ja Bcachefs'i arendaja pole ka veel valmistanud uuendatud pulli p\u00e4ringut, mis oleks vaba uute funktsioonide lisamisest ja keskenduks ainult vigade parandamisele.
