| Subject: SCSI: mpt2sas: _scsih_smart_predicted_fault uses GFP_KERNEL in interrupt context |
| |
| From: Anton Blanchard <anton@samba.org> |
| |
| commit f6a290b419a2675c4b77a6b0731cd2a64332365e upstream. |
| |
| _scsih_smart_predicted_fault is called in an interrupt and therefore |
| must allocate memory using GFP_ATOMIC. |
