btrfs-progs: tests: test for FST corruption detection/repair
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].
Changelog:
v3:
Handle fatal errors instead of BUG_ON() in patch[4, 6].
Thanks, Qu Wenruo and Nikolay Borisov.
Change comments and move declarations in patch[3]. Pointed by Qu Wenruo.
Handle corner case mentioned in patch[5] in walk_up_tree() not
process_one_leaf().
Test image are only with inode_extref now. Suggested by Qu Wenruo.
v2:
Resend with patches in right order.
