Looks like it. It's such a hack, I want to hide ;)
Sigh. I think I'd prefer to just go and make ->page_lock and ->private_lock irq-safe.
Or not proceed with this patch at all. If this is to be the only code which wishes to perform page list motion at interrupt time, perhaps it's not justifiable?
I really don't have a feeling for how valuable this is, nor do I know whether there will be other code which wants to perform page list manipulation at interrupt time.
In fact I also don't know where the whole AIO thing sits at present. Is it all done and finished? Is there more to come, and if so, what?? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
