NBSNEBIUS-356: retry io when io_submit return EAGAIN #1524

Open budevg opened 2 days ago

budevg commented 2 days ago

We discovered cases where aio_submit return with EAGAIN This can happen when aio subsystem is temporarily out of requests for example here https://elixir.bootlin.com/linux/latest/source/fs/aio.c#L2054

In this commit we start to handle EAGAIN as retryable error to avoid marking devices as broken
