Agree. Busy loop is only for test.
I will try the current git.
Committed two more rbd changes:
- Add support for rbd_invalidate_cache() (if it exists)
- Use rbd_aio_is_complete() instead of using fri->io_complete. The
latter should have some locking to ensure it's always seen, so it's
better to use the API provided function to determine whether this IO is
done or not.
Unless we often hit the complete race, I would not expect this to make
much of a difference. But it's worth testing in any case, especially
since my two attempts at setting up ceph + rbd have failed miserably. So
I still can't test myself.
