Sorry for late response, I was offline for several days due to national holidays. This patchset is good to me, but I'm not sure which path it should go through. Ordinarily, memory-failure patches go to linux-mm, but patch 3 depends on TRACE_DEFINE_ENUM patches, so this can go to linux-next directly, or go to linux-mm with depending patches. Steven, Andrew, which way do you like?
