55 | * The introduction of CEPH_FEATURE_OSD_SNAPMAPPER caused the feature | |
56 | * vector to evaluate to 64 bit ~0. To cope, we designate 1ULL << 63 | |
57 | * to mean 33 bit ~0, and introduce a helper below to do the | |
58 | * translation. | |
59 | * | |
60 | * This was introduced by ceph.git commit | |
