A minor change in the commit message of patch 2.
This patch series fixes a potential deadlock when creating a pcpu rt.
It happens when dst_alloc() decided to run gc. Something like this:
read_lock(&table->tb6_lock);
ip6_rt_pcpu_alloc()
=> dst_alloc()
=> ip6_dst_gc()
=> write_lock(&table
rt6_make_pcpu_route() is called under read_lock(&table->tb6_lock).
rt6_make_pcpu_route() calls ip6_rt_pcpu_alloc(rt) which then
calls dst_alloc(). dst_alloc() _may_ call ip6_dst_gc() which takes
the write_lock(&tabl->tb6_lock). A visualized version:
read_lock(&table->tb6_lock);
rt6_make_pcpu_rou
It is a prep work for fixing a potential deadlock when creating
a pcpu rt.
The current rt6_get_pcpu_route() will also create a pcpu rt if one does not
exist. This patch moves the pcpu rt creation logic into another function,
rt6_make_pcpu_route().
