netns xfrm: per-netns sysctls
Make
net.core.xfrm_aevent_etime
net.core.xfrm_acq_expires
net.core.xfrm_aevent_rseqth
net.core.xfrm_larval_drop
sysctls per-netns.
For that make net_core_path[] global, register it to prevent two
/proc/net/core antries and change initcall position -- xfrm_init() is called
from fs_initcall, so this one should be fs_initcall at least.
