From: Su Yue <suy.fnst@xxxxxxxxxxxxxx> This patchset can be fetched from my github(based on v4.17.1): https://github.com/Damenly/btrfs-progs/tree/lowmem_extref The patchset aims to support check and repair errors about inode_extref in lowmem mode. patch[1-2] let btrfs_unlink() detect inode_extref. patch[3] fixes a minor bug in check_dir_item due to my careless long ago. patch[4] fixes a bug about inconsistent path in check_fs_roots() under repair. patch[5] fixes a corner case about traversal of inode items. patch[6] enable inode_extref repair support and remove unnecessary checks. patch[7] add a test image, it can verify above patches except patch[3].
