Changelog ========= v4 -> v5: * Adjusted commit log for PATCH[1] * Dropped the last patch which deletes VFIO_EEH_PE_STATE_* from uapi/linux/vfio.h because we're uncertain if there're any one used or will use them in future as pointed by Alex.W. v3 -> v4: * Move constants for EEH PE states defined in uapi/linux/vfio.h to uapi/asm/eeh.h. v2 -> v3: * Use offsetofend(), instead of sizeof(struct vfio_eeh_pe_op) to calculate argument buffer size. v1 -> v2: * Use EEH_ERR_FUNC_{MIN,MAX} to validate PCI error function. * Put additional arguments for error injection to union in struct vfio_eeh_pe_op.
