Pages in the array are allocated/freed by caller of ceph_mdsc_do_request(). If request is interrupted, the pages can be freed while they are still being used by the request message.

The fix is force sending a getattr request to MDS if xattrs_version is 0. The getattr mask is set to CEPH_STAT_CAP_XATTR, so MDS knows client does not have xattr.
