I diskussionen om den seneste r\u00e6kke rettelser, der blev foresl\u00e5et til inklusion i kernen 6.11-rc5 af Bcachefs' forfatter, Linus Torvalds, n\u00e6vnte han, at han begynder at fortryde, at han har accepteret Bcachefs-filsystemet i kernen. Torvalds' utilfredshed skyldes, at Kent Overstreet, forfatteren af Bcachefs, sender for omfattende rettelser i de finale kandidater til udgivelser, som i realiteten ikke kun retter fejl, men ogs\u00e5 forts\u00e6tter udviklingen af funktionaliteten, selvom funktionelle \u00e6ndringer kun tillades i den indledende fase af udviklingen af en ny gren, og der i rc5-fasen kun accepteres enkelte sm\u00e5 rettelser, der ikke b\u00f8r overstige 100 linjer kode. <\/p>\n

Den indsendte patch til Bcachefs, som tilf\u00f8jede 1309 linjer og fjernede 671 linjer i 39 filer, omfattede udover fejlfinding ogs\u00e5 to betydelige \u00e6ndringer: st\u00f8tte til en ny datastruktur til at h\u00e5ndtere listen over frie elementer i cachen og muligheden for at transformere hash-tabellerne til cachen. Den nye struktur blev tilf\u00f8jet for at eliminere un\u00f8dvendige cachel\u00e5s og undg\u00e5 situationer, der kan f\u00f8re til l\u00e5s-konflikter under flertr\u00e5dede belastninger. <\/p>\n

Dette er ikke f\u00f8rste gang, at store rettelser til Bcachefs sendes efter \u00e6ndringsvinduet, og det er ikke f\u00f8rste gang, at mere omfattende funktionsudvidelser fremmes snarere end simple fejlfindinger, der brings frem via pull-anmodninger i de finale udviklingsfaser af en ny gren. Linus Torvalds svarede p\u00e5 den indsendte pull-anmodning: <\/p>\n

\u201eStop. Den sidste pull-anmodning var ogs\u00e5 stor. Denne pull-anmodning er ogs\u00e5 alt for omfattende, inkluderer ting, der ikke vedr\u00f8rer Bcachefs, og er endda p\u00e5 ingen m\u00e5de en regression. P\u00e5 et tidspunkt bliver \u201ereparation af noget\u201c bare til udvikling, og det er det \u00f8jeblik. Ingen i deres rette sind bruger Bcachefs og forventer stabilitet fra det, s\u00e5 hver bruger er et eksperimenteringsomr\u00e5de. Bcachefs patches er blevet en form for \u201estor udvikling under udgivelsescyklussen, ikke f\u00f8r\u201c, til det punkt, hvor jeg begynder at fortryde vedtagelsen af Bcachefs. Hvis Bcachefs ikke kan fungere ordentligt i overensstemmelse med udviklingsplanen for den oprindelige kerne, s\u00e5 burde det m\u00e5ske ikke v\u00e6re en del af den oprindelige kerne. Det begynder at v\u00e6re mere end bare sjovt. <\/p><\/blockquote>\n

Kent Overstreet responded that Bcachefs is definitely more reliable than Btrfs and he is working to make it more robust and reliable than XFS and EXT4, thanks to the implementation of an end to end data integrity mechanism. Kent also emphasized that the proposed changes are directly related to improving reliability, and if a bug in other core subsystems might just lead to crashes and reboots, in file systems the cost of a bug is very high and can lead to hidden data corruption that might only be noticed weeks later. <\/p>\n

Torvalds countered that there are still no major Linux distributions using Bcachefs, and pointed out that the rules for releasing Linux kernels should be followed, as there is a risk of introducing new bugs due to such large patches containing more than 1000 lines of code. Currently, the discussions regarding fixes to Bcachefs have not been accepted into the Linux kernel, and the Bcachefs developer has not yet prepared an updated version of the pull request that eliminates the addition of new functionality and focuses solely on bug fixes.
