From 84914b7ed1c5e0f3199a5a6997022758a70fcaff Mon Sep 17 00:00:00 2001 From: Paul Moore Date: Thu, 22 Apr 2010 14:46:18 -0400 Subject: selinux: Shuffle the sk_security_struct alloc and free routines The sk_alloc_security() and sk_free_security() functions were only being called by the selinux_sk_alloc_security() and selinux_sk_free_security() functions so we just move the guts of the alloc/free routines to the callers and eliminate a layer of indirection.
