This patch series enables lockdep for seqcount/seqlock structures, as well as provides the required cleanups to explicitly initialize the seqcount structures on u64_stat_sync users. In addition the last two patches in this provide fixes to some of the issues the new lockdep infrastructure caught. I'd greatly appreciate any thoughts or feedback on the series! Particularly on how the u64_stats_sync initialization changes should be merged. thanks -john Changeslog: v2: * Took Eric Dumazet's suggestion for a better ipv6 deadlock fix * Macro formatting improvements suggested by Ingo * Minor commit message tweaks Cc: Eric Dumazet Cc: Mathieu Desnoyers Cc: Steven Rostedt Cc: Peter Zijlstra Cc: Ingo Molnar Cc: Thomas Gleixner Cc: "David S.
