[PATCH 5.15.y 0/6] vfio: Interrupt eventfd hardening for 5.15.y

Alex Williamson <alex.williamson@xxxxxxxxxx> · Fri, 29 Mar 2024 16:59:36 -0600

Largely the same as the 6.1.y backports, minor context conflict still
using externs in header file and still using GFP_KERNEL rather than
GFP_KERNEL_ACCOUNT.  Also picking up 810cd4bb5345 ("vfio/pci: Lock
external INTx masking ops") which was previously included in Sasha's
6.1.y backports but here the prototype of vfio_pci_intx_mask() is
different.  Thanks,

Alex
