3.8.13.15 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Hannes Frederic Sowa <hannes@xxxxxxxxxxxxxxxxxxx> [ Upstream commit 7f88c6b23afbd31545c676dea77ba9593a1a14bf ] IPv6 stats are 64 bits and thus are protected with a seqlock. By not disabling bottom-half we could deadlock here if we don't disable bh and a softirq reentrantly updates the same mib.
