From 76e6eee03353f01bfca707d4dbb1f10a4ee27dc0 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 12 Mar 2009 14:35:43 -0600 Subject: cpumask: tsk_cpumask for accessing the struct task_struct's cpus_allowed. This allows us to change the representation (to a dangling bitmap or cpumask_var_t) without breaking all the callers: they can use tsk_cpumask() now and won't see a difference as the changes roll into linux-next.
