[PATCH 4.9 02/70] RDMA/rxe: Fix memleak in rxe_mem_init_user
From: Greg Kroah-Hartman
Date: Mon Sep 21 2020 - 13:05:26 EST
From: Dinghao Liu <dinghao.liu@xxxxxxxxxx>
[ Upstream commit e3ddd6067ee62f6e76ebcf61ff08b2c729ae412b ]
When page_address() fails, umem should be freed just like when
rxe_mem_alloc() fails.
Fixes: 8700e3e7c485 ("Soft RoCE driver")
