Each SCTP association can have up to 65535 input and output streams.
For each stream type an array of sctp_stream_in or sctp_stream_out
structures is allocated using kmalloc_array() function. This function
allocates physically contiguous memory regions, so this can lead
to allocation of memory regions of very high order, i.e.:

...

Given how useless SCTP streams are, does anything actually use
more than about 4?

Maybe Michael can help us with that. I'm also curious now.
