| Subject: qede: Fix gfp flags sent to rdma event node allocation |
| |
| From: Michal Kalderon <Michal.Kalderon@cavium.com> |
| |
| [ Upstream commit 090477e4acb31c5dd674940c7c01d4f16bd1ac41 ] |
| |
| A previous commit 4609adc27175 ("qede: Fix qedr link update") |
| added a flow that could allocate rdma event objects from an |
| interrupt path (link notification). Therefore the kzalloc call |
| should be done with GFP_ATOMIC. |
