OK, it starts making sense now. The message came from pagefault_out_of_memory which doesn't have gfp nor the required node information any longer. This suggests that VM_FAULT_OOM has been returned by the fault handler. So this hasn't been triggered by the page fault allocator. I am wondering whether this could be caused by the patch but the effect of that one should be limitted to the write (unlike the later version for -mm tree which hooks into the shmem as well). Will have to think about it some more. -- Michal Hocko SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe cgroups" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
