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->tb6_lock); /* oops */ Patch 1 and 2 are some prep works. Patch 3 is the fix. Original report: https://bugzilla.kernel.org/show_bug.cgi?id=102291 Steinar, the patches can also be applied to 4.2-rc5 (I just tried). Can you help to test them?
