Kirill Korotaev 4286229868 [PATCH] wrong error path in dup_fd() leading to oopses in RCU 
Wrong error path in dup_fd() - it should return NULL on error,
not an address of already freed memory :/

Triggered by OpenVZ stress test suite.

What is interesting is that it was causing different oopses in RCU like
below:
Call Trace:
   [<c013492c>] rcu_do_batch+0x2c/0x80

   [<c0103b54>] apic_timer_interrupt+0x1c/0x24
  Code:  Bad EIP value.
