[PATCH 0/2] userns: Creation logic fixes

[Eric W. Biederman]

So I have take a good hard stare at the problem, as well as sitting down
and writing some test code to verify the code works the way I think it
does.

The following two patches are how I think this bit of chaos needs to be
solved.  If folks could take a once over these patches and possibly test
them to confirm they fix your issues I would appreciate it.

Eric W. Biederman (2):
      unshare: Unsharing a thread does not require unsharing a vm
      userns,pidns: Force thread group sharing, not signal handler sharing.
