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