From 915076f70efad04bf6fc843970a3c7763487011a Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Thu, 24 Feb 2022 16:20:23 +0200 Subject: [PATCH] vfio/pci: Expose vfio_pci_core_aer_err_detected() Expose vfio_pci_core_aer_err_detected() to be used by drivers as part of their pci_error_handlers structure. Next patch for mlx5 driver will use it.
