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": "83d5cde47dedf01b6a4a4331882cbc0a7eea3c2e", "tree": "f8ba5e263717d35cd444fcc65898d2ed352af1ae", "parents": [ "7b021967c5e1463936042c8da72b550d3cabe9ac" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon Sep 21 17:01:13 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:25 2009 -0700" }, "message": "const: make block_device_operations const\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "9934c8c04561413609d2bc38c6b9f268cba774a4", "tree": "30dd8f7be54f9b2e03094de9cd03b6a9ee2909cd", "parents": [ "2343046826a8ca426b07601d9593ee046c298b68" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Fri May 08 11:54:16 2009 +0900" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Mon May 11 09:52:18 2009 +0200" }, "message": "block: implement and enforce request peek/start/fetch\n\nTill now block layer allowed two separate modes of request execution.\nA request is always acquired from the request queue via\nelv_next_request().

With his help, this was tracked down to bogus bio vectors\nwhich in turn was the result of a race condition between the\nreceive/transmit routines in the NBD driver.\n\nThe bug manifests itself like this:\n\nCPU0\t\t\t\tCPU1\ndo_nbd_request\n\tadd req to queuelist\n\tnbd_send_request\n\t\tsend req head\n\t\tfor each bio\n\t\t\tkmap\n\t\t\tsend\n\t\t\t\tnbd_read_stat\n\t\t\t\t\tnbd_find_request\n\t\t\t\t\tnbd_end_request\n\t\t\tkunmap\n\nWhen CPU1 finishes nbd_end_request, the request and all its associated\nbio\u0027s are freed. So when CPU0 calls kunmap whose argument is derived from\nthe last bio, it may crash.\n\nUnder normal circumstances, the race occurs only on the last bio. However,\nif an error is encountered on the remote NBD server (such as an incorrect\nmagic number in the request), or if there were a bug in the server, it is\npossible for the nbd_end_request to occur any time after the request\u0027s\naddition to the queuelist.\n\nThe following patch fixes this problem by making sure that requests are not\nadded to the queuelist until after they have been completed transmission.\n\nIn order for the receiving side to be ready for responses involving\nrequests still being transmitted, the patch introduces the concept of the\nactive request.\n\nWhen a response matches the current active request, its processing is\ndelayed until after the tranmission has come to a stop.\n\nThis has been tested by Janos and it has been successful in curing this\nrace condition.\n\nFrom: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\n\n Here is an updated patch which removes the active_req wait in\n nbd_clear_queue and the associated memory barrier.\n\n I\u0027ve also clarified this in the comment.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nCc: \u003cdjani22@dynamicweb.hu\u003e\nCc: Paul Clements \u003cPaul.Clements@SteelEye.com\u003e\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "8ffdc6550c47f75ca4e6c9f30a2a89063e035cf2", "tree": "a478b9acef5c66242a964154f7ad3a0ea750ef0f", "parents": [ "64100099ed22f71cce656c5c2caecf5c9cf255dc" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Fri Jan 06 09:49:03 2006 +0100" }, "committer": { "name": "Jens Axboe", "email": "axboe@suse.de", "time": "Fri Jan 06 09:49:03 2006 +0100" }, "message": "[BLOCK] add @uptodate to end_that_request_last() and @error to rq_end_io_fn()\n\nadd @uptodate argument to end_that_request_last() and @error\nto rq_end_io_fn(). there\u0027s no generic way to pass error code\nto request completion function, making generic error handling\nof non-fs request difficult (rq-\u003eerrors is driver-specific and\neach driver uses it differently). this patch adds @uptodate\nto end_that_request_last() and @error to rq_end_io_fn().\n\nfor fs requests, this doesn\u0027t really matter, so just using the\nsame uptodate argument used in the last call to\nend_that_request_first() should suffice. imho, this can also\nhelp the generic command-carrying request jens is working on.\n\nSigned-off-by: tejun heo \u003chtejun@gmail.com\u003e\nSigned-Off-By: Jens Axboe \u003caxboe@suse.de\u003e\n" }, { "commit": "40be0c28b33ff0821594a3fa7126354dfe6eccd1", "tree": "a62e93e866a2c7fdbe732adb634a6bba294beded", "parents": [ "4750e2c0c59e0c84c6c036b3d96ebd88365ae7ee" ], "author": { "name": "Lars Marowsky-Bree", "email": "lmb@suse.de", "time": "Sun May 01 08:59:07 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sun May 01 08:59:07 2005 -0700" }, "message": "[PATCH] nbd: Don\u0027t create all MAX_NBD devices by default all the time\n\nThis patches adds the \"nbds_max\" parameter to the nbd kernel module, which\nlimits the number of nbds allocated.
