[PATCH 4.14 164/222] smb3: allow stats which track session and share reconnects to be reset

From: Greg Kroah-Hartman
Date: Sun Nov 11 2018 - 17:33:01 EST


4.14-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.
