Browse source 
[ Upstream commit d314309425ad5dc1b6facdb2d456580fb5fa5e3a ]

Pack the fields to reduce the size of struct nfsd4_op, which is used
an array in struct nfsd4_compoundargs.

sizeof(struct nfsd4_op):
Before: /* size: 672, cachelines: 11, members: 5 */
After:  /* size: 640, cachelines: 10, members: 5 */
