4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Chuck Lever <chuck.lever@xxxxxxxxxx> commit d683cc49daf7c5afca8cd9654aaa1bf63cdf2ad9 upstream. When encoding the NFSACL SETACL operation, reserve just the estimated size of the ACL rather than a fixed maximum. This eliminates needless zero padding on the wire that the server ignores.
