Re: [PATCH v10 0/8] MR7797: ntdll: Wait for all pending operations to be cancelled in NtCancelIoFile[Ex]().

[Elizabeth Figura (＠zfigura)]

```
    /* FIXME: it would probably be nice to replace the "canceled" flag with a
     * single LIST_FOR_EACH_ENTRY_SAFE, but currently cancelling an async can
     * cause other asyncs to be removed via async_reselect() */
```

After 3/8 this comment in cancel_async() is off, since there's no "canceled" flag. The comment is still basically true, mind—it's ugly to have to restart the iteration every time, and having async_reselect() mess with other asyncs makes things awfully complicated, including here.
