F2FS Preparing FSERROR Reporting Support

Written by Michael Larabel in Linux Storage on 11 May 2026 at 08:26 AM EDT. Add A Comment
Introduced in Linux 7.0 was FSERROR as generic I/O error reporting infrastructure. Linux to that point had no standardized mechanism for reporting metadata corruption or file I/O errors to user-space with each file-system doing its own thing. The Flash-Friendly File-System (F2FS) is now the latest Linux file-system preparing for FSERROR usage.

Via the F2FS development "dev" branch is support for reporting F2FS errors to FSERROR. Integrating FSERROR into F2FS was just around 60 some lines of code.

The FSERROR integration can be found via this patch in the F2FS dev branch. With the code now in the dev branch, chances are this support will be merged for the upcoming Linux 7.2 kernel cycle.

Btrfs in Linux 7.1 added FSERROR support and XFS in Linux 7.0 was the debut file-system with FSERROR support along with EXT4. Other Linux file-systems likely to follow in using this standardized mechanism for reporting I/O errors.
