s390/qeth: add phys_to_virt() translation for AOB (86e7a4e4) · Commits · 戴 / test

Data addresses in the AOB are absolute, and need to be translated before being fed into kmem_cache_free(). Currently this phys_to_virt() is a no-op. Also see commit ("s390/qdio: fill SBALEs with absolute addresses"). Signed-off-by:
