While not as notable as [1]the nice EXT4 performance optimization making it into Linux 6.11 or features like [2]XFS real-time FITRIM and [3]self-healing Bcachefs on read I/O errors , the Bcachefs, F2FS, and Btrfs file-systems saw smaller updates for the Linux 6.11 kernel cycle.

The [4]F2FS pull request was sent out on Tuesday. F2FS this cycle adds FS_IOC_GETFSSYSFSPATH support, similar to [5]EXT4's FS_IOC_GETFSSYSFSPATH in Linux 6.10. F2FS also now enables ATGC dynamically in some cases and has various bug fixes and smaller improvements.

With the [6]exFAT driver changes merged last week there is a deadlock fix and then introducing support for [7]IDMAPPED mounts.

The [8]Btrfs changes were a bit heavier and included improvements to the background block group reclaim, automatically dropping the QGROUP of deleted subvolumes, mount option updates with "rescue=" mode improvements, memory allocation optimizations, and other improvements.

Hopefully for Linux 6.11 I'll finally have the time for carrying out a fresh Linux file-system performance comparison.
