- Summary
- ice: Do not use WQ_MEM_RECLAIM flag for workqueue
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ice: Do not use WQMEMRECLAIM flag for workqueue
When both ice and the irdma driver are loaded, a warning in checkflushdependency is being triggered. This is due to ice driver workqueue being allocated with the WQMEMRECLAIM flag and the irdma one is not.
According to kernel documentation, this flag should be set if the workqueue will be involved in the kernel's memory reclamation flow. Since it is not, there is no need for the ice driver's WQ to have this flag set so remove it.
Example trace:
