Subject: [PATCH v2 2/6] vfio/cpr-legacy: drop an erroneous assert
Date: Sun, 28 Sep 2025 04:54:28 -0400	[thread overview]
Message-ID: <20250928085432.40107-3-zhenzhong.duan@intel.com> (raw)
In-Reply-To: <20250928085432.40107-1-zhenzhong.duan@intel.com>

vfio_legacy_cpr_dma_map() is not only used in post_load on destination
but also error recovery path on source side. Assert it for destination
is wrong.

Fixes: 7e9f21411302 ("vfio/container: restore DMA vaddr")
