posix-aio-compat.c already implements a threadpool. It is geared towards using the QEMU block layer (BlockDriverState) but the pure ioctl codepath can be used without a BlockDriverState by passing NULL. So this could save you some effort, check out paio_submit(). ;) yeah, I realized that after looking at the code that I could have used that infrastructure. May be in the next release of this driver I will do that or more realistically when I write another driver, I will make use of it. However, I have one reservation about that code. Like you said, it is geared towards the QEMU block driver. I believe the code can be reworked to be more generic so that it can be reused elsewhere as is. ani ============================================================ The information contained in this message may be privileged and confidential and protected from disclosure.
