      "message": "dynamic_debug: process multiple debug-queries on a line\n\nInsert ddebug_exec_queries() in place of ddebug_exec_query().  It\nsplits the query string on [;\\n], and calls ddebug_exec_query() on\neach.  All queries are processed independent of errors, allowing a\nquery to fail, for example when a module is not installed.  Empty\nlines and comments are skipped.  Errors are counted, and the last\nerror seen (negative) or the number of callsites found (0 or positive)\nis returned.  Return code checks are altered accordingly.\n\nWith this, multiple queries can be given in ddebug_query, allowing\nmore selective enabling of callsites.  As a side effect, a set of\ncommands can be batched in:\n\n\tcat cmd-file \u003e $DBGMT/dynamic_debug/control\n\nWe dont want a ddebug_query syntax error to kill the dynamic debug\nfacility, so dynamic_debug_init() zeros ddebug_exec_queries()\u0027s return\ncode after logging the appropriate message, so that ddebug tables are\npreserved and $DBGMT/dynamic_debug/control file is created.  This\nwould be appropriate even without accepting multiple queries.\n\nThis patch also alters ddebug_change() to return number of callsites\nmatched (which typically is the same as number of callsites changed).\nddebug_exec_query() also returns the number found, or a negative value\nif theres a parse error on the query.\n\nSplitting on [;\\n] prevents their use in format-specs, but selecting\ncallsites on punctuation is brittle anyway, meaningful and selective\nsubstrings are more typical.\n\nNote: splitting queries on \u0027;\u0027 before handling trailing #comments\nmeans that a \u0027;\u0027 also terminates a comment, and text after the \u0027;\u0027 is\ntreated as another query.  This trailing query will almost certainly\nresult in a parse error and thus have no effect other than the error\nmessage.  The double corner case with unexpected results is:\n\n     ddebug_query\u003d\"func foo +p # enable foo ; +p\"\n\nSigned-off-by: Jim Cromie \u003cjim.cromie@gmail.com\u003e\nSigned-off-by: Jason Baron \u003cjbaron@redhat.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n"

      "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files.  percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed.  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"
