SmallHashDynamic<shash::Any, int> FdRefcountMgr::map_fd_

private

map for object id -> fd lookups, used when opening files in the cache. The fd is used as key in the refcount map.

SmallHashDynamic<int, FdRefcountInfo> FdRefcountMgr::map_refcount_

private

map for fd -> refcount lookups. A backreference to the object id is included in FdRefcountInfo in order to be able to remove the file descriptor from map_fd_.
