描述

If we transfer balance of buffer1 from allocator1 to allocator2, onRelease() should be called from allocator1.listener as well as the case that buffer1 is closed without transferring.

调研方向

检查分配和所有权转移的实现,然后查看 PR #11800 了解现有工作。当 buffer1 的所有权转移到 allocator2 时 allocator1.listener 接收到 onRelease(),就算完成;在 buffer1 关闭但未转移所有权时,目前已经会发生这种情况。
