From 67d1214551e800f9fe7dc7c47a346d2df0fafed5 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Wed, 27 Jun 2012 11:07:19 +0400 Subject: merge task_work and rcu_head, get rid of separate allocation for keyring case task_work and rcu_head are identical now; merge them (calling the result struct callback_head, rcu_head #define'd to it), kill separate allocation in security/keys since we can just use cred->rcu now.
