Subject: [PATCH 4.2 088/134] nfs: Fix truncated client owner id without proto type

4.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kinglong Mee <kinglongmee@...il.com>

commit 4a70316caef7d158445e672e146eb9f1b8c1aeee upstream.

The length of "Linux NFSv4.0 " is 14, not 10.

Without this patch, I get a truncated client owner id as,
"Linux NFSv4.0 ::1/::1"

With this patch,
"Linux NFSv4.0 ::1/::1 tcp"

Fixes: a319268891 ("nfs: make nfs4_init_nonuniform_client_string use a dynamically allocated buffer")
