Comment 3 for bug 1326473

This upstream commit, which is not in Lucid, removed the .ctl_name initializer
from netns_core_table:

  f8572d8 sysctl net: Remove unused binary sysctl code

Since Lucid's netns_core_table initializes .ctl_name, sysctl_check_table()
requires the .strategy field to be initialized. Other places using
proc_dointvec_minmax() for the .proc_handler seem to be using sysctl_intvec()
for the .strategy. I suppose the patch below would be the correct fix, but
would like someone from the kernel team to take over from here.
