[Qemu-devel] [PATCH 2/2] memory: abort if a memory region is destroyed during a transaction |
Date: |

Destroying a memory region is illegal within a transaction, as until
the transaction is committed, the memory core may hold references to
the region. Add an assert to check for violations of this rule.
