Subject: [PATCH V3 mlx5-next 12/13] vfio/pci: Expose vfio_pci_aer_err_detected()
Date: Sun, 24 Oct 2021 11:30:18 +0300	[thread overview]
Message-ID: <20211024083019.232813-13-yishaih@nvidia.com> (raw)
In-Reply-To: <20211024083019.232813-1-yishaih@nvidia.com>

Expose vfio_pci_aer_err_detected() to be used by drivers as part of
their pci_error_handlers structure.

Next patch for mlx5 driver will use it.
