option that will be added to the nfsuserd daemon in a future commit. It modifies the cache used by NFSv4 for name<-->id translation (both username/uid and group/gid) to support this. When "-manage-gids" is set, the server looks up each uid for the RPC and uses the list of groups cached in the server instead of the list of groups provided in the RPC request. The cached group list is acquired for the cache by the nfsuserd daemon via getgrouplist(3). This avoids the 16 groups limit for the list in the RPC request. Since the cache is now used for every RPC when "-manage-gids" is enabled, the code also modifies the cache to use a separate mutex for each hash list instead of a single global mutex.
