Ilya Dryomov db2196a589 libceph: eliminate overflows in ceph_calc_file_object_mapping() 
bl, stripeno and objsetno should be u64 -- otherwise large enough files
get corrupted.  How large depends on file layout:

- 4M-objects layout (default): any file over 16P
- 64K-objects layout (smallest possible object size): any file over 512T

Only CephFS is affected, rbd doesn't use ceph_calc_file_object_mapping()
yet.  Fortunately, CephFS has a max_file_size configurable, the default
for which is way below both of the above numbers.

Reimplement the logic from scratch with no layout validation -- it's
done on the MDS side.
