The patch is still horridly mangled by your email client.

The implementation cheerfully ignores my earlier comment: "The
conventional way of doing this is to attempt the kmalloc with
__GFP_NOWARN and if that failed, fall back to vmalloc()."

This code has existed for ten years and this is the first time anyone
has encountered this problem.  Rather than mucking around with the
seq_file code to attempt to fix this, it would be better to fix the
calling code.
