Adrian,
The patch looks fine. But instead of marking some functions directly as static
i would like to use SCTP_STATIC macro which is defined as static within kernel.
This allows us to export certain internal static functions to our user-level
sctp test framework that uses the kernel implementation.
I will submit this patch with the above change as part of next SCTP update.
Thanks
Sridhar
