Fetched in submodule path 'ceph-erasure-code-corpus', but it did not contain 2d7d78b9cc52e8a9529d8cc2d2954c7d375d5dd7. Direct fetching of that commit failed.

It'd be great to look into it, as it should allow much quicker cloning (which is useful for CI).
Note that using '--depth 1' seems to work fine, and also reduces size nicely (several hundred of MBs less to clone).
