| Subject: RDMA/rxe: Fix memleak in rxe_mem_init_user |
| |
| From: Dinghao Liu <dinghao.liu@zju.edu.cn> |
| |
| [ Upstream commit e3ddd6067ee62f6e76ebcf61ff08b2c729ae412b ] |
| |
| When page_address() fails, umem should be freed just like when |
| rxe_mem_alloc() fails. |
| |
| Fixes: 8700e3e7c485 ("Soft RoCE driver") |
