This function compiles to 147 bytes of machine code. 13 callsites.
I'm no expert on SCTP events, but quick reading of SCTP docs tells me that
SCTP events are not happening on every packet.
They are ASSOC_CHANGE, PEER_ADDR_CHANGE, REMOTE_ERROR and such.
Does not look performance critical.

Please fix the alignment here --------^
the const should start after the '(' column, as it was before the patch.
Thanks

This now misaligns the next line after the inline removal.
Can you please run your patches through checkpatch?

CHECK: Alignment should match open parenthesis
