Btrfs Brings Experimental Remap-Tree Feature & More In Linux 7.0 (www.phoronix.com)

Among the pull requests merged today on this first day of the Linux 7.0 merge window are the many Btrfs file-system feature updates.

David Sterba sent in the Btrfs feature pull in advance of the Linux 6.19 stable release and thus among the early merges for kicking off the Linux 7.0 cycle. There aren't any noted performance optimizations specifically this cycle but a lot of other feature work some of which may help performance like enabling direct I/O for larger block sizes when greater than the kernel's page size.

Whoah.

Please correct me if I'm wrong but this can streamline incremental backups from filesystem level snapshots of a live system no?
