48 * The introduction of CEPH_FEATURE_OSD_SNAPMAPPER caused the feature
49 * vector to evaluate to 64 bit ~0. To cope, we designate 1ULL << 63
50 * to mean 33 bit ~0, and introduce a helper below to do the
51 * translation.
52 *
53 * This was introduced by ceph.git commit
54 * 9ea02b84104045c2ffd7e7f4e7af512953855ecd v0.58-657-g9ea02b8
55 * and fixed by ceph.git commit
56 * 4255b5c2fb54ae40c53284b3ab700fdfc7e61748 v0.65-263-g4255b5c
