Subject: [PATCH 3.16 112/305] smb3: allow stats which track session and
 share reconnects to be reset

3.16.63-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Steve French <stfrench@...rosoft.com>

commit 2c887635cd6ab3af619dc2be94e5bf8f2e172b78 upstream.

Currently, "echo 0 > /proc/fs/cifs/Stats" resets all of the stats
except the session and share reconnect counts.  Fix it to
reset those as well.
