explains:\n\n - various misc stuff\n\n - Most of the rest of MM: memcg, threaded hugepages, others.\n\n - cpumask\n\n - kexec\n\n - kdump\n\n - some direct-io performance tweaking\n\n - radix-tree optimisations\n\n - new selftests code\n\n A note on this: often people will develop a new userspace-visible\n feature and will develop userspace code to exercise/test that\n feature. Then they merge the patch and the selftest code dies.\n Sometimes we paste it into the changelog. Sometimes the code gets\n thrown into Documentation/(!).\n\n This saddens me. So this patch creates a bare-bones framework which\n will henceforth allow me to ask people to include their test apps in\n the kernel tree so we can keep them alive. Then when people enhance\n or fix the feature, I can ask them to update the test app too.\n\n The infrastruture is terribly trivial at present - let\u0027s see how it\n evolves.\n\n - checkpoint/restart feature work.\n\n A note on this: this is a project by various mad Russians to perform\n c/r mainly from userspace, with various oddball helper code added\n into the kernel where the need is demonstrated.\n\n So rather than some large central lump of code, what we have is\n little bits and pieces popping up in various places which either\n expose something new or which permit something which is normally\n kernel-private to be modified.\n\n The overall project is an ongoing thing. I\u0027ve judged that the size\n and scope of the thing means that we\u0027re more likely to be successful\n with it if we integrate the support into mainline piecemeal rather\n than allowing it all to develop out-of-tree.\n\n However I\u0027m less confident than the developers that it will all\n eventually work! So what I\u0027m asking them to do is to wrap each piece\n of new code inside CONFIG_CHECKPOINT_RESTORE. So if it all\n eventually comes to tears and the project as a whole fails, it should\n be a simple matter to go through and delete all trace of it.\n\nThis lot pretty much wraps up the -rc1 merge for me.\n\n* akpm: (96 commits)\n unlzo: fix input buffer free\n ramoops: update parameters only after successful init\n ramoops: fix use of rounddown_pow_of_two()\n c/r: prctl: add PR_SET_MM codes to set up mm_struct entries\n c/r: procfs: add start_data, end_data, start_brk members to /proc/$pid/stat v4\n c/r: introduce CHECKPOINT_RESTORE symbol\n selftests: new x86 breakpoints selftest\n selftests: new very basic kernel selftests directory\n radix_tree: take radix_tree_path off stack\n radix_tree: remove radix_tree_indirect_to_ptr()\n dio: optimize cache misses in the submission path\n vfs: cache request_queue in struct block_device\n fs/direct-io.c: calculate fs_count correctly in get_more_blocks()\n drivers/parport/parport_pc.c: fix warnings\n panic: don\u0027t print redundant backtraces on oops\n sysctl: add the kernel.ns_last_pid control\n kdump: add udev events for memory online/offline\n include/linux/crash_dump.h needs elf.h\n kdump: fix crash_kexec()/smp_send_stop() race in panic()\n kdump: crashk_res init check for /sys/kernel/kexec_crash_size\n ...\n" }, { "commit": "85bbddc37b2bf947a577d572b1c4c23bf829217f", "tree": "07e483b13f93d6e5eb08d4423648a0812b41b3fe", "parents": [ "274343ad3e63c4dcee6744a75b5553940de4a0f6" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Thu Jan 12 17:20:46 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 12 20:13:12 2012 -0800" }, "message": "selftests: new x86 breakpoints selftest\n\nBring a first selftest in the relevant directory.

myapp -L\n PID LWP TTY TIME CMD\n25118 25118 ? 00:00:00 myapp\n25118 25119 ? 00:00:00 myapp:worker\n\nperf record -e cs -c 1 -fo /tmp/perf.data -p 25118 -- sleep 10\nperf report --stdio -i /tmp/perf.data\n 100.00% myapp:worker [kernel.kallsyms] [k] perf_event_task_sched_out\n\nThe process name is set to the name of the last thread it finds for the\nprocess.\n\nThe Problem:\nperf-top and perf-record both create a thread_map of threads to be\nmonitored. That map is used in perf_event__synthesize_thread_map which\nloops over the entries in thread_map and calls __event__synthesize_thread\nto generate COMM and MMAP events.\n\n__event__synthesize_thread calls perf_event__synthesize_comm which opens\n/proc/pid/status, reads the name of the task and its thread group id.\nThat\u0027s all fine. The problem is that it then reads /proc/pid/task and\ngenerates COMM events for each task it finds - but using the name found\nin /proc/pid/status where pid is the thread of interest.\n\nThe end result (looping over thread_map + synthesizing comm events for\neach thread each time) means the name of the last thread processed sets\nthe name for all threads in the process - which is not good for\nmultithreaded processes with named threads.\n\nThe Fix:\nperf_event__synthesize_comm has an input argument (full) that decides\nwhether to process task entries for each pid it is passed. It currently\nnever set to 0 (perf_event__synthesize_comm has a single caller and it\nalways passes the value 1). Let\u0027s fix that.\n\nAdd the full input argument to __event__synthesize_thread which passes\nit to perf_event__synthesize_comm. For thread/process monitoring set full\nto 0 which means COMM and MMAP events are only generated for the pid\npassed to it. For system wide monitoring set full to 1 so that COMM events\nare generated for all threads in a process.\n\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/1324578603-12762-2-git-send-email-dsahern@gmail.com\nSigned-off-by: David Ahern \u003cdsahern@gmail.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "c2857cb4a855aba0c3f826bcd0dfef72abb0995b", "tree": "ea8ba66b4202505a4762ffcc7e9351711ad5c069", "parents": [ "9cc9e091ed4c70535309dd9336a5ea5c2c5920aa" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Thu Dec 22 22:06:59 2011 -0500" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Thu Dec 22 22:06:59 2011 -0500" }, "message": "ktest: Fix compare script to test if options are not documented\n\nThe compare script compare-ktest-sample.pl checks for options\nthat are defined in ktest.pl and not documented in samples.conf,\nas well as samples in samples.conf that are not used in ktest.pl.\n\nWith the switch to the hash format to initialize the ktest variables\nthe compare script needs to be updated to handle the change.\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "9cc9e091ed4c70535309dd9336a5ea5c2c5920aa", "tree": "514c7d65b55f5cc3df3487bbc89a79dc35d1fd24", "parents": [ "b5f4aea687797bf9ab24f59643f88f82443b01fa" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Thu Dec 22 21:37:22 2011 -0500" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Thu Dec 22 22:02:35 2011 -0500" }, "message": "ktest: Detect typos in option names\n\nIt becomes quite annoying when you go to run a test and then\nrealize that you typed an option name wrong, and the test starts\ndoing the default action and not what you expected it to do.\n\nIt is even more annoying when you wake up the next day after\nrunning the test over night when you discover this.\n\nBy testing if all options specified in a config file are\nused by either ktest or were used in one of the option\u0027s values\nwe can see if there are any dangling options that were not used.\nIn such a case, show the user the options that were not used\nand ask them if they want to continue or not.\n\nThe option IGNORE_UNUSED was also added to allow the user to\noverride this feature.\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "b5f4aea687797bf9ab24f59643f88f82443b01fa", "tree": "2f131628e273d7be4ac84a6e788db8667ac20119", "parents": [ "4f43e0dcafe89205d3c266fed196fd417a9fe3de" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Thu Dec 22 21:33:55 2011 -0500" }, "committer": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Thu Dec 22 22:00:52 2011 -0500" }, "message": "ktest: Have all values be set by defaults\n\nCurrently the patchcheck, bisect, and config_bisect variables\nare only able to be set per test.
