Hi, how about this patch pls?

I'm not convinced that this is a necessary feature for the mainline
kernel.

It also needs more review, from at least other security folk, and ideally
also from fs/vfs folk.

Thank you James.

Why does NFSARK want this supportr?  Are its users asking for it?  (I
couldn't find the distro, btw).

Yes, it's user asks for acl for ipc,
It is a distro by nfschina.

* In general, it can give a more fine grained and flexible DAC to msg queue obj.
* NFSARK(A distro) wants all posix ipc objects to support ACL, including mqueue.
* Posix semphore and shmem both support ACL, but mqueue as one of the
three basic ipc doesn't.
* At least, it may save one note sentence for MQ_OVERVIEW(7)   ^_^

This patch adds ACL supports to mqueue filesystem.
Based on Linux 3.0.4.

Why is this necessary, and who is planning to use it?

Are any distros likely to enable this?
