The\ncase that I witnessed personally was on MIPS:\n\nhttp://lkml.org/lkml/2010/5/30/4\n\nIf (can_use_console() \u003d\u003d 0), printk() will spool its output to log_buf\nand it will be visible in \"dmesg\", but that output will NOT be echoed to\nthe console until somebody calls release_console_sem() from a CPU that\nis online. Therefore, the boot time messages from the new CPU can get\nstuck in \"limbo\" for a long time, and might suddenly appear on the\nscreen when a completely unrelated event (e.g. \"eth0: link is down\")\noccurs.\n\nThis patch modifies the console code so that any pending messages are\nautomatically flushed out to the console whenever a CPU hotplug\noperation completes successfully or aborts.\n\nThe issue was seen on 2.6.34.\n\nOriginal patch by Kevin Cernekee with cleanups by akpm and additional fixes\nby Santosh Shilimkar.

And at\nthis point it really does become very natural to start to peel off some of\nthe error labels and move them into the helper functions - now the\n\"truncated\" case is gone, and is handled inside that setup function\ninstead.\n\nSo maybe you don\u0027t like this approach, and it does make the variable\naccesses a bit longer, but I don\u0027t think unreadably so. And the patch\nreally does look big and scary, but there really should be absolutely no\nsemantic changes - most of it was a trivial and mindless rename.\n\nIn fact, it was so mindless that I on purpose kept the existing helper\nfunctions looking like this:\n\n- err \u003d check_modinfo(mod, sechdrs, infoindex, versindex);\n+ err \u003d check_modinfo(mod, info.sechdrs, info.index.info, info.index.vers);\n\nrather than changing them to just take the \"info\" pointer. IOW, a second\nphase (if you think the approach is ok) would change that calling\nconvention to just do\n\n\terr \u003d check_modinfo(mod, \u0026info);\n\n(and same for \"layout_sections()\", \"layout_symtabs()\" etc.) Similarly,\nwhile right now it makes things _look_ bigger, with things like this:\n\n\tversindex \u003d find_sec(hdr, sechdrs, secstrings, \"__versions\");\n\nbecoming\n\n\tinfo-\u003eindex.vers \u003d find_sec(info-\u003ehdr, info-\u003esechdrs, info-\u003esecstrings, \"__versions\");\n\nin the new \"setup_module_info()\" function, that\u0027s again just a result of\nit being a search-and-replace patch. By using the \u0027info\u0027 pointer, we could\njust change the \u0027find_sec()\u0027 interface so that it ends up being\n\n\tinfo-\u003eindex.vers \u003d find_sec(info, \"__versions\");\n\ninstead, and then we\u0027d actually have a shorter and more readable line. So\nfor a lot of those mindless variable name expansions there\u0027s would be room\nfor separate cleanups.\n\nI didn\u0027t move quite everything in there - if we do this to layout_symtabs,\nfor example, we\u0027d want to move the percpu, symoffs, stroffs, *strmap\nvariables to be fields in that module_info structure too. But that\u0027s a\nmuch smaller patch, I moved just the really core stuff that is currently\nbeing set up and used in various parts.\n\nBut even in this rough form, it removes close to 70 lines from that\nfunction (but adds 22 lines overall, of course - the structure definition,\nthe helper function declarations and call-sites etc etc).\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n" }, { "commit": "44032e631691adf1f406843d5e54deb795973ff7", "tree": "e9cb4f72974386a2b174bf6e21f41be9aece7a10", "parents": [ "22e268ebecc549f1b1907f114cb44d6044bdee3c" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Aug 05 12:59:05 2010 -0600" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Thu Aug 05 12:59:06 2010 +0930" }, "message": "module: reduce stack usage for each_symbol()\n\nAnd now that I\u0027m looking at that call-chain (to see if it would make sense\nto use some other more specific lock - doesn\u0027t look like it: all the\nreaders are using RCU and this is the only writer), I also give you this\ntrivial one-liner.

First, if a wakeup\nevent occurs exactly when /sys/power/state is being written to, it\nmay be delivered to user space right before the freezer kicks in, so\nthe user space consumer of the event may not be able to process it\nbefore the system is suspended. Second, if a wakeup event occurs\nafter user space has been frozen, it is not generally guaranteed that\nthe ongoing transition of the system into a sleep state will be\naborted.\n\nTo address these issues introduce a new global sysfs attribute,\n/sys/power/wakeup_count, associated with a running counter of wakeup\nevents and three helper functions, pm_stay_awake(), pm_relax(), and\npm_wakeup_event(), that may be used by kernel subsystems to control\nthe behavior of this attribute and to request the PM core to abort\nsystem transitions into a sleep state already in progress.\n\nThe /sys/power/wakeup_count file may be read from or written to by\nuser space. Reads will always succeed (unless interrupted by a\nsignal) and return the current value of the wakeup events counter.\nWrites, however, will only succeed if the written number is equal to\nthe current value of the wakeup events counter. If a write is\nsuccessful, it will cause the kernel to save the current value of the\nwakeup events counter and to abort the subsequent system transition\ninto a sleep state if any wakeup events are reported after the write\nhas returned.\n\n[The assumption is that before writing to /sys/power/state user space\nwill first read from /sys/power/wakeup_count. Next, user space\nconsumers of wakeup events will have a chance to acknowledge or\nveto the upcoming system transition to a sleep state. Finally, if\nthe transition is allowed to proceed, /sys/power/wakeup_count will\nbe written to and if that succeeds, /sys/power/state will be written\nto as well. Still, if any wakeup events are reported to the PM core\nby kernel subsystems after that point, the transition will be\naborted.]\n\nAdditionally, put a wakeup events counter into struct dev_pm_info and\nmake these per-device wakeup event counters available via sysfs,\nso that it\u0027s possible to check the activity of various wakeup event\nsources within the kernel.\n\nTo illustrate how subsystems can use pm_wakeup_event(), make the\nlow-level PCI runtime PM wakeup-handling code use it.\n\nSigned-off-by: Rafael J.

Because wake_affine() uses this\nstructure only to compute load-balancing heuristics, there is no reason\nto acquire either of the two locks.\n\nTherefore, this commit introduces an RCU read-side critical section that\nstarts before the first call to task_group() and ends after the last use\nof the \"tg\" pointer returned from task_group(). Thanks to Li Zefan for\npointing out the need to extend the RCU read-side critical section from\nthat proposed by the original patch.\n\nSigned-off-by: Daniel J Blueman \u003cdaniel.blueman@gmail.com\u003e\nSigned-off-by: Paul E.
