From bf7491f1be5e125eece2ec67e0f79d513caa6c7e Mon Sep 17 00:00:00 2001 From: Benjamin Coddington Date: Sun, 7 Dec 2014 16:05:48 -0500 Subject: [PATCH] nfsd4: fix xdr4 count of server in fs_location4 Fix a bug where nfsd4_encode_components_esc() incorrectly calculates the length of server array in fs_location4--note that it is a count of the number of array elements, not a length in bytes.
