v2:
- clean up do_recover_object()
- introduce SD_RES_STALE_OBJ to indicate that sheep may return a stale object
- rebase onto upstream
The first patch is a preparation for the succeeding patches. The next 2 patches
improves performance of object recovery. The next 4 patches are helpful to find
the latest objects when recovering sheepdog cluster manually. The next 2
patches fixes fatal problems of object recovery, and the last patch prints
errors in sheep.log when sheepdog may lose data.
MORITA Kazutaka (10):
sheep: do breadth first search in recover_object_from_replica()
sheep: don't try to recover from working directory
sheep: recover from local if possible
sheep: move objects to stale direcotry before starting recovery
md: kick recovery outside of md_lock context
sheep: try to recover only from the target epoch
tests/010: remove stale objects from working directory contents
sheep: recover objects in the ordered worker thread
sheep: split struct recovery_work
sheep: show error message when object may be lost
