Cover letter [PATCH 0/7][RFC] pid: changes to support audit
These are a number of patches inspired by ebiederman's container work that were included by me 2013-08-20 as the patchset:
RFC: steps to make audit pid namespace-safe
They have been seperated out for the pid maintainer since there are no direct dependencies from the audit pid namespace patchset with the exception of:
pid: get pid_t ppid of task in init_pid_ns

In particular, there is discussion around read-only task_struct::pid here:

Richard Guy Briggs (7):
pid: change task_struct::pid to read-only
compiler: CONST_CAST makes writing const vars easier and obvious
pid: use the CONST_CAST macro instead to write to const
task_struct::pid
pid: modify task_tgid_nr to work without task->tgid.
pid: rewrite task helper function is_global_init() avoiding task->pid
pid: mark struct task const in helper functions
pid: get pid_t ppid of task in init_pid_ns
