With a was number of callsites sctp_add_cmd_sf wrapper bloats kernel by some amount. Due to unlikely tracking allyesconfig, with the initial result were around ~7kB (thus caught my attention) while a non-debug config produced only ~2.3kB effect. I (ij) proposed first a patch to uninline it but Vlad responded with a patch that removed the only sctp_add_cmd call which is wrapped by sctp_add_cmd_sf (I wasn't sure if I could do that). I did minor cleanup to Vlad's patch. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S.
