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.
I’m daily driving it on my main desktop and several laptops with full disk encryption and zero issues, although I am not a power user of some of the complex functions btrfs offers, I just slap it on a whole disk and dump all my files into one big partition and that’s pretty much good enough for me. I should try subvolumes at some point I guess, IDK.
