Patchset can be fetched from github: https://github.com/adam900710/linux/tree/write_time_tree_checker Which is based on v5.0-rc1 tag. This patchset has the following two features: - Tree block validation output enhancement * Output validation failure timing (write time or read time) * Always output tree block level/key mismatch error message This part is already submitted and reviewed. - Write time tree block validation check To catch memory corruption either from hardware or kernel. Example output would be: BTRFS critical (device dm-3): corrupt leaf: root=2 block=1350630375424 slot=68, bad key order, prev (10510212874240 169 0) current (1714119868416 169 0) BTRFS error (device dm-3): write time tree block corruption detected BTRFS critical (device dm-3): corrupt leaf: root=2 block=1350630375424 slot=68, bad key order, prev (10510212874240 169 0) current (1714119868416 169 0) BTRFS error (device dm-3): write time tree block corruption detected BTRFS: error (device dm-3) in btrfs_commit_transaction:2220: errno=-5 IO failure (Error while writing out transaction) BTRFS info (device dm-3): forced readonly BTRFS warning (device dm-3): Skipping commit of aborted transaction. BTRFS: error (device dm-3) in cleanup_transaction:1839: errno=-5 IO failure BTRFS info (device dm-3): delayed_refs has NO entry Changelog: v2: - Unlock locked pages in lock_extent_buffer_for_io() for error handling. - Added Reviewed-by tags. v3: - Remove duplicated error message. - Use IS_ENABLED() macro to replace #ifdef. - Added Reviewed-by tags.
