From df0ce17331e2501dbffc060041dfc6c5f85227b5 Mon Sep 17 00:00:00 2001 From: Sargun Dhillon Date: Thu, 29 Mar 2018 01:28:23 +0000 Subject: security: convert security hooks to use hlist This changes security_hook_heads to use hlist_heads instead of the circular doubly-linked list heads. This should cut down the size of the struct by about half. In addition, it allows mutation of the hooks at the tail of the callback list without having to modify the head. The longer-term purpose of this is to enable making the heads read only.
