From ff2266cddd69f5e0c9d5121ed9218d2f694406cc Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Mon, 15 Apr 2013 03:27:17 +0000 Subject: net: sctp: remove sctp_ep_common struct member 'malloced' There is actually no need to keep this member in the structure, because after init it's always 1 anyway, thus always kfree called. This seems to be an ancient leftover from the very initial implementation from 2.5 times. Only in case the initialization of an association fails, we leave base.malloced as 0, but we nevertheless kfree it in the error path in sctp_association_new().
