Re: [PATCH] pstore: ramoops: support pmsg size larger than kmalloc limitation

[Yuxiao Zhang]

Thanks for the review Kees.

>And yes, Greg's questions are all good -- fixing syntax and adding size
details in the commit log would be appreciated.

Sure, will send another patch to address this.

Hi Guilherme, thanks for testing this patch.

>But when I tried to increase the record size in ramoops, I got this error: https://termbin.com/b12e

What record type are you testing? I should have mention that this patch is only for pmsg use case on ramoops (I mentioned it in the original thread but need to start a new one due to format issue).

>Also - Kees certainly knows that way better, but - are we 100% sure that
the region for pstore can be non-contiguous? For some reason, I always
thought this was a requirement

Right, that is why this patch only touches the pstore ram path, I am not sure how things will go if it is block device backed.

Thanks,
