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].

btrfs-progs: lowmem: search key of root again after check_fs_root()
under repair
btrfs-progs: lowmem: continue to check item in last slot while
