(This is a revision of the patch series in http://lkml.org/lkml/2009/7/2/464 )

The following series adds a "cgroup.procs" file to each cgroup that reports
unique tgids rather than pids, and fixes a pid namespace bug in the existing
"tasks" file that could cause readers in different namespaces to interfere
with one another.

This patch series implements a superset of the functionality of (and was
written at the same time as) Li Zefan's pid namespace bugfix patch (from
http://lkml.org/lkml/2009/7/1/559 ). These patches can either be rewritten to
be applied on top of Li's patch, or be applied as they are with Li's patch


Ben Blum (3):
      Quick vmalloc vs kmalloc fix to the case where array size is too large
      Ensures correct concurrent opening/reading of pidlists across pid namespaces
      Adds a read-only "procs" file similar to "tasks" that shows only unique tgids
