That's ok, it could happen before as well. What's wrong with that? > Original copied below, feel free to take it. You are just sitting and sleeping until someone drops the last reference to the module. What if userspace grabs a reference from sysfs? That could never return, I don't think you want to stall that out. I'd prefer not having 2 things determining the lifecycle of a single object, that's messy, and not needed at all. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
