Subject: TUN problems (regression?)

[CC'ing netdev in case this is a known problem I just missed ...]

Hi Jason,

I started doing some more testing with the multiqueue TUN changes and I ran 
into a problem when running tunctl: running it once w/o arguments works as 
expected, but running it a second time results in failure and a 
kmem_cache_sanity_check() failure.  The problem appears to be very repeatable 
on my test VM and happens independent of the LSM/SELinux fixup patches.

Have you seen this before?
