Bcachefs Merged Into the Linux 6.7 Kernel
The new open-source, copy-on-write file system known as Bcachefs has been successfully merged into the Linux 6.7 kernel. "Given the past struggles to get Bcachefs mainlined, I certainly didn't expect to see Linus Torvalds act so soon on merging it," writes Phoronix's Michael Larabel. "But after it spent all of the 6.6 cycle within Linux-Next, overnight Linus Torvalds did in fact land this new file-system developed by Kent Overstreet." From a Slashdot story published on Friday August 21, 2015: Bcachefs is a new open-source file-system derived from the bcache Linux kernel block layer cache. Bcachefs was announced by Kent Overstreet, the lead Bcache author. Bcachefs hopes to provide performance like XFS/EXT4 while having features similar to Btrfs and ZFS. The bachefs on-disk format hasn't yet been finalized and the code isn't yet ready for the Linux kernel. That said, initial performance results are okay and "It probably won't eat your data -- but no promises." Features so far for Bcachefs are support for multiple devices, built-in caching/tiering, CRC32C checksumming, and Zlib transparent compression. Support for snapshots is to be worked on.
