Hello, Linus.

Sorry about the late pull request. I ended up staying offline longer than
planned. This pull request contains the cgroup.procs permission check fixes
so that they use the credentials at the time of open rather than write,
which also fixes the cgroup namespace lifetime bug.

While the changes seem safe to me and they tested fine, this is on the
invasive side for a pull request this late, so please feel free to ignore.
I'll include them when the merge window opens.

Thanks and happy new year.
