Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "12ee3c0a0ac42bed0939420468fd35f5cdceae4f", "tree": "c97f04d93fcca34d9ab7548f2b5070235202d52d", "parents": [ "f0eae0ed3b7d4182a6b4dd03540a738518ea3163" ], "author": { "name": "David Rientjes", "email": "rientjes@google.com", "time": "Wed Mar 10 14:50:21 2010 -0800" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Fri Mar 19 07:12:22 2010 -0700" }, "message": "driver core: numa: fix BUILD_BUG_ON for node_read_distance\n\nnode_read_distance() has a BUILD_BUG_ON() to prevent buffer overruns when\nthe number of nodes printed will exceed the buffer length.\n\nEach node only needs four chars: three for distance (maximum distance is\n255) and one for a seperating space or a trailing newline.\n\nSigned-off-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "3701cde6e35245e26f63252f46c62e8a790fa996", "tree": "f4fde55198c52db97f46286a41275d66c081e29c", "parents": [ "e1a7e29a266ba3313a873d302b352521403bd155" ], "author": { "name": "Andi Kleen", "email": "andi@firstfloor.org", "time": "Tue Jan 05 12:48:04 2010 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Sun Mar 07 17:04:47 2010 -0800" }, "message": "sysdev: Use sysdev_class attribute arrays in node driver\n\nConvert the node driver to sysdev_class attribute arrays.

So any particular CPU has some\nmemory in each zone structure which belongs to itself. Even if that CPU is\nnot local to that zone.\n\nSo the patch relocates the pagesets for each cpu to the node that is nearest\nto the cpu instead of allocating the pagesets in the (possibly remote) target\nzone. This means that the operations to manage pages on remote zone can be\ndone with information available locally.\n\nWe play a macro trick so that non-NUMA pmachines avoid the additional\npointer chase on the page allocator fastpath.\n\nAIM7 benchmark on a 32 CPU SGI Altix\n\nw/o patches:\nTasks jobs/min jti jobs/min/task real cpu\n 1 484.68 100 484.6769 12.01 1.97 Fri Mar 25 11:01:42 2005\n 100 27140.46 89 271.4046 21.44 148.71 Fri Mar 25 11:02:04 2005\n 200 30792.02 82 153.9601 37.80 296.72 Fri Mar 25 11:02:42 2005\n 300 32209.27 81 107.3642 54.21 451.34 Fri Mar 25 11:03:37 2005\n 400 34962.83 78 87.4071 66.59 588.97 Fri Mar 25 11:04:44 2005\n 500 31676.92 75 63.3538 91.87 742.71 Fri Mar 25 11:06:16 2005\n 600 36032.69 73 60.0545 96.91 885.44 Fri Mar 25 11:07:54 2005\n 700 35540.43 77 50.7720 114.63 1024.28 Fri Mar 25 11:09:49 2005\n 800 33906.70 74 42.3834 137.32 1181.65 Fri Mar 25 11:12:06 2005\n 900 34120.67 73 37.9119 153.51 1325.26 Fri Mar 25 11:14:41 2005\n 1000 34802.37 74 34.8024 167.23 1465.26 Fri Mar 25 11:17:28 2005\n\nwith slab API changes and pageset patch:\n\nTasks jobs/min jti jobs/min/task real cpu\n 1 485.00 100 485.0000 12.00 1.96 Fri Mar 25 11:46:18 2005\n 100 28000.96 89 280.0096 20.79 150.45 Fri Mar 25 11:46:39 2005\n 200 32285.80 79 161.4290 36.05 293.37 Fri Mar 25 11:47:16 2005\n 300 40424.15 84 134.7472 43.19 438.42 Fri Mar 25 11:47:59 2005\n 400 39155.01 79 97.8875 59.46 590.05 Fri Mar 25 11:48:59 2005\n 500 37881.25 82 75.7625 76.82 730.19 Fri Mar 25 11:50:16 2005\n 600 39083.14 78 65.1386 89.35 872.79 Fri Mar 25 11:51:46 2005\n 700 38627.83 77 55.1826 105.47 1022.46 Fri Mar 25 11:53:32 2005\n 800 39631.94 78 49.5399 117.48 1169.94 Fri Mar 25 11:55:30 2005\n 900 36903.70 79 41.0041 141.94 1310.78 Fri Mar 25 11:57:53 2005\n 1000 36201.23 77 36.2012 160.77 1458.31 Fri Mar 25 12:00:34 2005\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Shobhit Dayal \u003cshobhit@calsoftinc.com\u003e\nSigned-off-by: Shai Fultheim \u003cShai@Scalex86.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "4b45099b75832434c5113b9aed1499f8a69d13d5", "tree": "dbb6cf4a3937120be0cfd6f4699926fa4689ac8d", "parents": [ "f409661877a25d11c2495bcd879807f17c286684" ], "author": { "name": "Keiichiro Tokunaga", "email": "tokunaga.keiich@jp.fujitsu.com", "time": "Sun May 08 21:28:53 2005 +0900" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Jun 20 15:15:29 2005 -0700" }, "message": "[PATCH] Driver core: unregister_node() for hotplug use\n\nThis adds a generic function \u0027unregister_node()\u0027.\nIt is used to remove objects of a node going away\nfor hotplug.
