buf_pool_invalidate(): Properly wait for
os_aio_wait_until_no_pending_writes() to ensure so that there
are no pending buf_page_t::write_complete() or buf_page_write_complete()
operations. This will avoid a failure of buf_pool.assert_all_freed().
This bug should affect debug builds only. At this point, the
buf_pool.flush_list should be clear and all changes should have
been written out. The loop around buf_LRU_scan_and_free_block() should
have eventually completed and freed all pages as soon as
buf_page_t::write_complete() had a chance to release the page latches.
It is worth noting that buf_flush_wait() is working as intended.
As soon as buf_flush_page_cleaner() invokes
buf_pool.get_oldest_modification() it will observe that
buf_page_t::write_complete() had assigned oldest_modification_ to 1,
and remove such blocks from buf_pool.flush_list. Upon reaching
buf_pool.flush_list.count=0 the buf_flush_page_cleaner() will mark
itself idle and wake buf_flush_wait() by broadcasting
buf_pool.done_flush_list.
