Subject: [PATCH 4.8 68/96] IB/rxe: Fix a memory leak in rxe_qp_cleanup()

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

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

From: Bart Van Assche <bart.vanassche@...disk.com>

commit e259934d4df7f99f2a5c2c4f074f6a55bd4b1722 upstream.

A socket is associated with every QP by the rxe driver but sock_release()
is never called. Add a call to sock_release() in rxe_qp_cleanup().

Fixes: commit 8700e3e7c48A5 ("Add Soft RoCE driver")
