Subject: [PATCH 5.10.y 5.4.y 0/6] vfio: Interrupt eventfd hardening for 5.10.y, 5.4.y
Date: Mon, 1 Apr 2024 10:52:54 -0600 [thread overview]
Message-ID: <20240401165302.3699643-1-alex.williamson@redhat.com> (raw)
This is nearly identical to the v5.15 backport, the only difference is
the split to struct vfio_pci_core_device hasn't occurred yet, so we need
to use the original vfio_pci_device object instead.
NB. The fsl-mc driver doesn't exist on v5.4.y, therefore the last patch
in the series should be dropped against v5.4.
v4.19.y does not include IRQF_NO_AUTOEN, so this is as far as I intend
to go with these. Thanks,
Alex
