[5.4] route6/fib6 : correct the program not to do panic even if a kmem_cache_create is failed

Solution Verified - Updated -

Issue

  • [5.4] route6/fib6 : correct the program not to do panic even if a kmem_cache_create is failed
  • If the kmem_cache_create fails, the kernel will panic.
  • It is acceptable if the system is booting. but if the ipv6 protocol is compiled as a module and it is loaded after the system has booted, we don't want to panic instead  of just failing to initialize the protocol.

Environment

  • Red Hat Enterprise Linux 5 Update 4
  • kernel-2.6.18-164.el5
