From: Al Viro Date: Tue, 21 Nov 2006 01:05:23 +0000 (-0800) Subject: [SCTP]: Switch ->cmp_addr() and sctp_cmp_addr_exact() to net-endian. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5f242a13e8505e0f3efd3113da6e029f6e7dfa32;p=linux-beck.git [SCTP]: Switch ->cmp_addr() and sctp_cmp_addr_exact() to net-endian. instances of ->cmp_addr() are fine with switching both arguments to net-endian; callers other than in sctp_cmp_addr_exact() (both as ->cmp_addr(...) and direct calls of instances) adjusted; sctp_cmp_addr_exact() switched to net-endian itself and adjustment is done in its callers Signed-off-by: Al Viro Signed-off-by: David S.
