    /* Use static buffer, for the caller is holding oom_lock. */
    static char buf[PAGE_SIZE];
    ....
    seq_buf_init(&s, buf, sizeof(buf));
    memory_stat_format(memcg, &s);
    seq_buf_do_printk(&s, KERN_INFO);

}

This is a callosal stack allocation, given that our fleet only has 8K stacks. :-)

That's a static allocation though :)

Ah right, did not notice it was static (and ignored the comment)
