I was looking at this again, I think it's more appropriate to use
req->rc->capacity at this point like you did in the first version of the
patch.
I had suggested msize in the common p9_parse_header function because
that'd let us accept zc requests where the size in the pdu could be
bigger than capacity, but this isn't the case in p9_check_errors.
If you're ok with this I'll edit your commit directly, this is less work
for me than having to check a new patch.
Thanks,
