The Linux 7.1 merge window has received updates for three major filesystems: F2FS, EXT4, and XFS. All three updates focus primarily on bug fixes rather than new features. F2FS changes address race conditions, memory safety issues (use-after-free), garbage collection robustness, and folio management. XFS brings only bug fixes and code refactoring. EXT4 also focuses on fixes, with the notable addition of preparatory work for future IOmap support for buffered writes. The most significant filesystem work in Linux 7.1 remains the Btrfs enhancements and NTFS resurrection.
