Subject: Possible bug for ring-mapped provided buffer
Date: Thu, 9 Jun 2022 15:53:57 +0800	[thread overview]
Message-ID: <[email protected]> (raw)

Hi all,
I haven't done tests to demonstrate it. It is for partial io case, we
don't consume/release the buffer before arm_poll in ring-mapped mode.
But seems we should? Otherwise ring head isn't moved and other requests
may take that buffer. What do I miss?

Regards,
Hao
