For example:\n\n\tint main(void)\n\t{\n\t\tint child, status;\n\n\t\tchild \u003d fork();\n\t\tif (!child) {\n\t\t\tint ret;\n\n\t\t\tassert(ptrace(PTRACE_TRACEME, 0,0,0) \u003d\u003d 0);\n\n\t\t\tret \u003d pause();\n\t\t\tprintf(\"pause: %d %m\\n\", ret);\n\n\t\t\treturn 0x23;\n\t\t}\n\n\t\tsleep(1);\n\t\tassert(ptrace(PTRACE_KILL, child, 0,0) \u003d\u003d 0);\n\n\t\tassert(child \u003d\u003d wait(\u0026status));\n\t\tprintf(\"wait: %x\\n\", status);\n\n\t\treturn 0;\n\t}\n\nprints \"pause: -1 Unknown error 514\", -ERESTARTNOHAND leaks to the\nuserland. In this case sys_pause() is buggy as well and should be\nfixed.\n\nI do not know what was the original rationality behind PTRACE_KILL.\nThe man page is simply wrong and afaics it was always wrong. Imho\nit should be deprecated, or may be it should do send_sig(SIGKILL)\nas Denys suggests, but in any case I do not think that the current\nbehaviour was intentional.\n\nNote: there is another problem, ptrace_resume() changes -\u003eexit_code\nand this can race with SIGKILL too. Eventually we should change ptrace\nto not use -\u003eexit_code.\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\n" }, { "commit": "19426a8f810752b4218e59b1e2187f33e255f7bc", "tree": "dd88adc38ef98a10b1eea952f16d7480411e2409", "parents": [ "0f1493a60167cf6333626456d3fc8aff4e6fa237", "8af088710d1eb3c980e0ef3779c8d47f3f217b48" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 08:58:50 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 08:58:50 2011 -0700" }, "message": "Merge branch \u0027timers-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027timers-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n posix-timers: RCU conversion\n" }, { "commit": "162a7e7500f9664636e649ba59defe541b7c2c60", "tree": "f44d4e480975d7f2c4bd4fd8625dbdb81eb04ade", "parents": [ "95dde501907b06e7203c74f8435acfdab9eb2659" ], "author": { "name": "Mike Travis", "email": "travis@sgi.com", "time": "Tue May 24 17:13:20 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 25 08:39:48 2011 -0700" }, "message": "printk: allocate kernel log buffer earlier\n\nOn larger systems, because of the numerous ACPI, Bootmem and EFI messages,\nthe static log buffer overflows before the larger one specified by the\nlog_buf_len param is allocated.

the\nCLOCK_REALTIME and CLOCK_MONOTONIC constants. Now the hrtimer bases\nhave their own enumeration due to the gap between CLOCK_MONOTONIC and\nCLOCK_BOOTTIME. So we can be more clever as most timers end up on the\nCLOCK_MONOTONIC base due to the virtue of POSIX declaring that\nrelative CLOCK_REALTIME timers are not affected by time changes. In\ndesktop environments this is slowly changing as applications switch to\nabsolute timers, but I\u0027ve observed empty CLOCK_REALTIME bases often\nenough.

In addition,\nwatchdog_thresh was reduced to 10 seconds as suggested by Ingo\nMolnar.\n\nSigned-off-by: Mandeep Singh Baines \u003cmsb@chromium.org\u003e\nCc: Marcin Slusarz \u003cmarcin.slusarz@gmail.com\u003e\nCc: Don Zickus \u003cdzickus@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nLink: http://lkml.kernel.org/r/1306127423-3347-4-git-send-email-msb@chromium.org\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nLKML-Reference: \u003c20110517071642.GF22305@elte.hu\u003e\n" }, { "commit": "586692a5a5fc5740c8a46abc0f2365495c2d7c5f", "tree": "bc08228e67a968d83691c9efc5ea1feda9e6f98b", "parents": [ "e04ab2bc41b35c0cb6cdb07c8443f91aa738cf78" ], "author": { "name": "Mandeep Singh Baines", "email": "msb@chromium.org", "time": "Sun May 22 22:10:22 2011 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon May 23 11:58:59 2011 +0200" }, "message": "watchdog: Disable watchdog when thresh is zero\n\nThis restores the previous behavior of softlock_thresh.\n\nCurrently, setting watchdog_thresh to zero causes the watchdog\nkthreads to consume a lot of CPU.\n\nIn addition, the logic of proc_dowatchdog_thresh and\nproc_dowatchdog_enabled has been factored into proc_dowatchdog.\n\nSigned-off-by: Mandeep Singh Baines \u003cmsb@chromium.org\u003e\nCc: Marcin Slusarz \u003cmarcin.slusarz@gmail.com\u003e\nCc: Don Zickus \u003cdzickus@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nLink: http://lkml.kernel.org/r/1306127423-3347-3-git-send-email-msb@chromium.org\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nLKML-Reference: \u003c20110517071018.GE22305@elte.hu\u003e\n" }, { "commit": "e04ab2bc41b35c0cb6cdb07c8443f91aa738cf78", "tree": "511efcd50f74c0a3cf28cf5c68eaa5e70b45fbc7", "parents": [ "824c6b7f6294101f30e141117def224a56c203e6" ], "author": { "name": "Mandeep Singh Baines", "email": "msb@chromium.org", "time": "Sun May 22 22:10:21 2011 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon May 23 11:58:58 2011 +0200" }, "message": "watchdog: Only disable/enable watchdog if neccessary\n\nDon\u0027t take any action on an unsuccessful write to /proc.\n\nSigned-off-by: Mandeep Singh Baines \u003cmsb@chromium.org\u003e\nCc: Marcin Slusarz \u003cmarcin.slusarz@gmail.com\u003e\nCc: Don Zickus \u003cdzickus@redhat.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nLink: http://lkml.kernel.org/r/1306127423-3347-2-git-send-email-msb@chromium.org\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "824c6b7f6294101f30e141117def224a56c203e6", "tree": "c609d4c12a1d5af1ceccb5c1c2275df2947d9e2c", "parents": [ "3ac1bbcf13c56a19927df670f429eb0c3c11f8e5" ], "author": { "name": "Mandeep Singh Baines", "email": "msb@chromium.org", "time": "Sun May 22 22:10:20 2011 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon May 23 11:58:58 2011 +0200" }, "message": "watchdog: Fix rounding bug in get_sample_period()\n\nIn get_sample_period(), softlockup_thresh is integer divided by\n5 before the multiplication by NSEC_PER_SEC.

Micro-arch performance costs:\n\nExperiment was to run Ingo\u0027s pipe_test_100k 200 times with the\ntask pinned to one cpu. I measured instruction, cycles and\nstalled-cycles for the runs. See:\n\n http://thread.gmane.org/gmane.linux.kernel/1129232/focus\u003d1129389\n\nfor more info.\n\n-tip (baseline):\n\n Performance counter stats for \u0027/root/load-scale/pipe-test-100k\u0027 (200 runs):\n\n 964,991,769 instructions # 0.82 insns per cycle\n # 0.33 stalled cycles per insn\n # ( +- 0.05% )\n 1,171,186,635 cycles # 0.000 GHz ( +- 0.08% )\n 306,373,664 stalled-cycles-backend # 26.16% backend cycles idle ( +- 0.28% )\n 314,933,621 stalled-cycles-frontend # 26.89% frontend cycles idle ( +- 0.34% )\n\n 1.122405684 seconds time elapsed ( +- 0.05% )\n\n-tip+patches:\n\n Performance counter stats for \u0027./load-scale/pipe-test-100k\u0027 (200 runs):\n\n 963,624,821 instructions # 0.82 insns per cycle\n # 0.33 stalled cycles per insn\n # ( +- 0.04% )\n 1,175,215,649 cycles # 0.000 GHz ( +- 0.08% )\n 315,321,126 stalled-cycles-backend # 26.83% backend cycles idle ( +- 0.28% )\n 316,835,873 stalled-cycles-frontend # 26.96% frontend cycles idle ( +- 0.29% )\n\n 1.122238659 seconds time elapsed ( +- 0.06% )\n\nWith this patch, instructions decrease by ~0.10% and cycles\nincrease by 0.27%. This doesn\u0027t look statistically significant.\nThe number of stalled cycles in the backend increased from\n26.16% to 26.83%. This can be attributed to the shifts we do in\nc_d_m() and other places. The fraction of stalled cycles in the\nfrontend remains about the same, at 26.96% compared to 26.89% in -tip.\n\n2.

This is the case, because\nthe drivers\u0027 .freeze() callbacks are executed after the hibernate\nmemory preallocation has been carried out and the preallocated amount\nof memory may be too small to cover the new driver allocations.\nUnfortunately, the drivers\u0027 .prepare() callbacks also are executed\nafter the hibernate memory preallocation has completed, so they are\nnot suitable for allocating additional memory either. Thus the only\nway a driver can safely allocate memory during hibernation is to use\na hibernate/suspend notifier.
