H A D | async.c | 023ca420 Wed Apr 14 15:02:47 CDT 2021 Stefan Hajnoczi <stefanha@redhat.com> util/async: print leaked BH name when AioContext finalizes BHs must be deleted before the AioContext is finalized. If not, it's a bug and probably indicates that some part of the program still expects the BH to run in the future. That can lead to memory leaks, inconsistent state, or just hangs. Unfortunately the assert(flags & BH_DELETED) call in aio_ctx_finalize() is difficult to debug because the assertion failure contains no information about the BH! Use the QEMUBH name field added in the previous patch to show a useful error when a leaked BH is detected.
