Re: [PATCH v19 06/14] PCI/AER: Introduce AER-CXL protocol error kfifo

> CXL VH RAS handling requires a path for the AER driver to hand off CXL
> protocol errors to cxl_core for logging and recovery before PCIe AER
> recovery tears down the device. Introduce drivers/pci/pcie/aer_cxl_vh.c to
> implement this handoff via a kfifo-backed work item.
