Description
It would be useful to speed up "lfs migrate", "lfs mirror extend", and "lfs mirror resync" to use asynchronous Direct IO (AIO/DIO via libaio) to do the data copying
This should use the same mechanism as lustre/tests/aiocp.c to have a producer/consumer queue and submits some number of AIO read requests, and then submit the write requests when the reads finish.
