| H A D | async.c | 8dd48650 Mon Mar 06 03:15:06 CST 2023 Paolo Bonzini <pbonzini@redhat.com> async: update documentation of the memory barriers
Ever since commit 8c6b0356b539 ("util/async: make bh_aio_poll() O(1)",
2020-02-22), synchronization between qemu_bh_schedule() and aio_bh_poll()
is happening when the bottom half is enqueued in the bh_list; not
when the flags are set. Update the documentation to match.
