[PATCH 0/3] btrfs-progs: Do proper extent item generation repair

[Qu Wenruo <wqu@xxxxxxxx>]

Before this patchset, the only way to repair invalid extent item
generation is to use --init-extent-tree, which is really a bad idea.

To rebuild the whole extent tree just for one corrupted extent item?
I must be insane at that time.

This patch introduces the proper extent item generation repair
functionality for both mode, and alter existing test case to also test
repair.

  btrfs-progs: check/original: Repair extent item generation
  btrfs-progs: tests/fsck-044: Enable repair test for invalid extent
    item generation
