From 41f9d29f09ca0b22c3631e8a39676e74cda9bcc0 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 26 Jun 2012 22:10:04 +0400 Subject: trimming task_work: kill ->data get rid of the only user of ->data; this is _not_ the final variant - in the end we'll have task_work and rcu_head identical and just use cred->rcu, at which point the separate allocation will be gone completely.
