As for not having any max pages for FMR it's really annoying.
What do you think about exposing max_fast_reg_page_list_len to
limit also for FMRs? We can also rename it to max_reg_page_list_len
to get rid of the FRWR association.
Thoughts?
I have no issue with your proposal, but I would rather get this fixed and adjust the API with an additional fix. I suspect we probably want to mark this fix stable.
I did audit the kernel ULPs for FMR vs. FRMR usage and the only one that looked at max_fast_reg_page_list_len unconditionally was iser.
Thomas, can you verify this patch and reply with a Tested-by:
Meanwhile, I will audit kernel providers for which ones besides qib do not support the extensions and FMR.
So what is the page_list limitation for qib? I want to prepare some
patches...
