		unsigned int	base,
		unsigned int *	aclcnt,
		struct posix_acl **	pacl
	)

nfsacl_decode - Decode an NFSv3 ACL

: xdr_buf containing XDR'd ACL data to decode : byte offset in xdr_buf where XDR'd ACL begins : count of ACEs in decoded posix_acl : buffer in which to place decoded posix_acl

Returns the length of the decoded ACL in bytes, or a negative errno value.

		unsigned int	base,
		struct inode *	inode,
		struct posix_acl *	acl,
		int	encode_entries,
		int	typeflag
	)

nfsacl_encode - Encode an NFSv3 ACL

: destination xdr_buf to contain XDR encoded ACL : byte offset in xdr_buf where XDR'd ACL begins : inode of file whose ACL this is : posix_acl to encode : whether to encode ACEs as well : ACL type: NFS_ACL_DEFAULT or zero

Returns size of encoded ACL in bytes or a negative errno value.
