Allowing typesafe storage uids and gids. Add a helper pace_gt for sorting posix_acl_entries. In struct posix_user_ace_state to replace uid with a union of kuid_t uid and kgid_t gid. Remove all initializations of the deprecated posic_acl_entry e_id field. Which is not present when user namespaces are enabled. Split find_uid into two functions find_uid and find_gid that work in a typesafe manner. In nfs4xdr update nfsd4_encode_fattr to deal with the changes in struct nfs4_ace. Rewrite nfsd4_encode_name to take a kuid_t and a kgid_t instead of a generic id and flag if it is a group or a uid. Replace the group flag with a test for a valid gid. Modify nfsd4_encode_user to take a kuid_t and call the modifed nfsd4_encode_name. Modify nfsd4_encode_group to take a kgid_t and call the modified nfsd4_encode_name. Modify nfsd4_encode_aclname to take an ace instead of taking the fields of an ace broken out. This allows it to detect if the ace is for a user or a group and to pass the appropriate value while still being typesafe. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W.
