[PATCH 4.19 263/361] smb3: allow stats which track session and share reconnects to be reset

[Greg Kroah-Hartman]

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

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

From: Steve French <stfrench@xxxxxxxxxxxxx>

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.
