Subject: Re: [PATCH] ring-buffer: Preserve true payload lengths in long data events
Date: Wed, 08 Apr 2026 00:45:52 +0800	[thread overview]
Message-ID: <177558035265.28431.15146377071345343168@163.com> (raw)
In-Reply-To: <20260407114812.580c27d5@gandalf.local.home>

Thanks for the clarification.

I understand the design boundary now: the ring buffer metadata is
supposed to describe the allocated record size, not the requested
payload size. Given that, I will stop pushing this ring-buffer
approach.

If there is a valid fix here, it should be done at the event layer
for the users that need the true payload length, not in the generic
ring buffer code.

Thanks,
Cao Ruichuang
