Bcachefs "pitches itself as a filesystem that 'doesn't eat your data'," writes the open source/Linux blog It's FOSS. Although it was last October that Bcachefs developer Kent Overstreet was restricted from participating in the Linux 6.13 kernel development cycle (after ending a mailing list post with "Get your head examined. And get the fuck out of here with this shit.") And now with the upcoming Linux kernel 6.17 release, Linus Torvalds has decided to drop Bcachefs support, they report, "owing to growing tensions" with Overstreet: The decision follows a series of disagreements over how fixes and changes for it were submitted during the 6.16 release cycle... Kent filed a pull request to add a new feature called "journal-rewind". It was meant to improve bcachefs repair functionality, but it landed during the release candidate (RC) phase, a time usually reserved for bug fixes, not new features, as Linus pointed out. [Adding "I remain steadfastly convinced that anybody who uses bcachefs is expecting it to be experimental. They had better."] Theodore Ts'o, a long-time kernel developer and maintainer of ext4, also chimed in, saying that Kent's approach risks introducing regressions, especially when changes affect sensitive parts of a filesystem like journaling. He reminded Kent that the rules around the merge window have been a long-standing consensus in the kernel community, and it's Linus's job to enforce them. After some more back and forth, Kent pushed back, arguing that the rules around the merge window aren't absolute and should allow for flexibility, even more so when user data is at stake. He then went ahead and resubmitted the patch, citing instances from XFS and Btrfs where similar fixes made it into the kernel during RCs. Linus merged it into his tree, but ultimately decided to drop Bcachefs entirely in the 6.17 merge window. To which Kent responded by clarifying that he wasn't trying to shut Linus out of Bcachefs' decisions, stressing that he values Linus's input... This of course follows the great Torvalds-Overstreet "filesystem people never learn" throwdown back in April.Read more of this story at Slashdot.
