From d683cc49daf7c5afca8cd9654aaa1bf63cdf2ad9 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Tue, 26 May 2015 11:53:52 -0400 Subject: NFS: Fix size of NFSACL SETACL operations 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. Fixes: ee5dc7732bd5 ('NFS: Fix "kernel BUG at fs/nfs/nfs3xdr.c:1338!"')
