Subject: Re: [net-next:master 20/29] net/sctp/output.c:185:21: warning:
 format '%lu' expects argument of type 'long unsigned int', but argument 4
 has type 'size_t {aka unsigned int}'


I fixed this as follows:

====================
[PATCH] sctp: Fix warning in sctp_packet_transmit_chunk()

size_t objects should be printed with %Z printf format.
