All records carry a 64 bit timestamp, the syslog facility\n and priority in the record header.\n\n- Records consume almost the same amount, sometimes less memory than\n the traditional byte stream buffer (if printk_time is enabled). The record\n header is 16 bytes long, plus some padding bytes at the end if needed.\n The byte-stream buffer needed 3 chars for the syslog prefix, 15 char for\n the timestamp and a newline.\n\n- Buffer management is based on message sequence numbers. When records\n need to be discarded, the reading heads move on to the next full\n record. Unlike the byte-stream buffer, no old logged lines get\n truncated or partly overwritten by new ones. Sequence numbers also\n allow consumers of the log stream to get notified if any message in\n the stream they are about to read gets discarded during the time\n of reading.\n\n- Better buffered IO support for KERN_CONT continuation lines, when printk()\n is called multiple times for a single line. The use of KERN_CONT is now\n mandatory to use continuation; a few places in the kernel need trivial fixes\n here. The buffering could possibly be extended to per-cpu variables to allow\n better thread-safety for multiple printk() invocations for a single line.\n\n- Full-featured syslog facility value support. Different facilities\n can tag their messages. All userspace-injected messages enforce a\n facility value \u003e 0 now, to be able to reliably distinguish them from\n the kernel-generated messages. Independent subsystems like a\n baseband processor running its own firmware, or a kernel-related\n userspace process can use their own unique facility values.

When a cpu gets\nofflined it schedules the idle process which, before killing its own cpu, will\ncall tick_nohz_stop_sched_tick(). That function in turn will call\nprintk_needs_cpu() in order to check if the local tick can be disabled. On\noffline cpus this function should naturally return 0 since regardless if the\ntick gets disabled or not the cpu will be dead short after. That is besides the\nfact that __cpu_disable() should already have made sure that no interrupts on\nthe offlined cpu will be delivered anyway.\n\nIn this case it prevents tick_nohz_stop_sched_tick() to call\nselect_nohz_load_balancer(). No idea if that really is a problem. However what\nmade me debug this is that on 2.6.32 the function get_nohz_load_balancer() is\nused within __mod_timer() to select a cpu on which a timer gets enqueued. If\nprintk_needs_cpu() returns 1 then the nohz_load_balancer cpu doesn\u0027t get\nupdated when a cpu gets offlined. It may contain the cpu number of an offline\ncpu. In turn timers get enqueued on an offline cpu and not very surprisingly\nthey never expire and cause system hangs.\n\nThis has been observed 2.6.32 kernels. On current kernels __mod_timer() uses\nget_nohz_timer_target() which doesn\u0027t have that problem. However there might be\nother problems because of the too early exit tick_nohz_stop_sched_tick() in\ncase a cpu goes offline.\n\nEasiest way to fix this is just to test if the current cpu is offline and call\nprintk_tick() directly which clears the condition.\n\nAlternatively I tried a cpu hotplug notifier which would clear the condition,\nhowever between calling the notifier function and printk_needs_cpu() something\ncould have called printk() again and the problem is back again.
