get a .llseek operation so we can make\nnonseekable_open the default for future file operations without a\n.llseek pointer.\n\nThe three cases that we can automatically detect are no_llseek, seq_lseek\nand default_llseek. For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time. Existing drivers can be converted\nto do the same when the maintainer knows for certain that no user code\nrelies on calling seek on the device file.\n\nThe generated code is often incorrectly indented and right now contains\ncomments that clarify for each added line why a specific variant was\nchosen. In the version that gets submitted upstream, the comments will\nbe gone and I will manually fix the indentation, because there does not\nseem to be a way to do that using coccinelle.\n\nSome amount of new code is currently sitting in linux-next that should get\nthe same modifications, which I will do at the end of the merge window.\n\nMany thanks to Julia Lawall for helping me learn to write a

This forces use of a fresh scatterlist for each DMA\noperation, which makes recycling a single scatterlist impossible.\n\nChange the behavior of the kfifo_dma functions to match the usage of the\ndma_map_sg function. This means that users must respect the returned\nnents value. The sample code is updated to reflect the change.\n\nThis bug is trivial to cause: call kfifo_dma_in_prepare() such that it\nprepares a scatterlist with a single entry comprising the whole fifo.\nThis is the case when you map the entirety of a newly created empty fifo.\nThis causes the setup_sgl() function to mark the first scatterlist entry\nas the end of the chain, no matter what comes after it.\n\nAfterwards, add and remove some data from the fifo such that another call\nto kfifo_dma_in_prepare() will create two scatterlist entries. It returns\nnents\u003d2. However, due to the previous sg_mark_end() call, sg_is_last()\nwill now return true for the first scatterlist element. This causes the\nsample code to print a single scatterlist element when it should print\ntwo.\n\nBy removing the call to sg_mark_end(), we make the API as similar as\npossible to the DMA mapping API. All users are required to respect the\nreturned nents.\n\nSigned-off-by: Ira W.

"message": "tracing: Let tracepoints have data passed to tracepoint callbacks\n\nThis patch adds data to be passed to tracepoint callbacks.\n\nThe created functions from DECLARE_TRACE() now need a mandatory data\nparameter. For example:\n\nDECLARE_TRACE(mytracepoint, int value, value)\n\nWill create the register function:\n\nint register_trace_mytracepoint((void(*)(void *data, int value))probe,\n void *data);\n\nAs the first argument, all callbacks (probes) must take a (void *data)\nparameter. So a callback for the above tracepoint will look like:\n\nvoid myprobe(void *data, int value)\n{\n}\n\nThe callback may choose to ignore the data parameter.\n\nThis change allows callbacks to register a private data pointer along\nwith the function probe.\n\n\tvoid mycallback(void *data, int value);\n\n\tregister_trace_mytracepoint(mycallback, mydata);\n\nThen the mycallback() will receive the \"mydata\" as the first parameter\nbefore the args.\n\nA more detailed example:\n\n DECLARE_TRACE(mytracepoint, TP_PROTO(int status), TP_ARGS(status));\n\n /* In the C file */\n\n DEFINE_TRACE(mytracepoint, TP_PROTO(int status), TP_ARGS(status));\n\n [...]\n\n trace_mytracepoint(status);\n\n /* In a file registering this tracepoint */\n\n int my_callback(void *data, int status)\n {\n\tstruct my_struct my_data \u003d data;\n\t[...]\n }\n\n [...]\n\tmy_data \u003d kmalloc(sizeof(*my_data), GFP_KERNEL);\n\tinit_my_data(my_data);\n\tregister_trace_mytracepoint(my_callback, my_data);\n\nThe same callback can also be registered to the same tracepoint as long\nas the data registered is different. Note, the data must also be used\nto unregister the callback:\n\n\tunregister_trace_mytracepoint(my_callback, my_data);\n\nBecause of the data parameter, tracepoints declared this way can not have\nno args. That is:\n\n DECLARE_TRACE(mytracepoint, TP_PROTO(void), TP_ARGS());\n\nwill cause an error.\n\nIf no arguments are needed, a new macro can be used instead:\n\n DECLARE_TRACE_NOARGS(mytracepoint);\n\nSince there are no arguments, the proto and args fields are left out.\n\nThis is part of a series to make the tracepoint footprint smaller:\n\n text\t data\t bss\t dec\t hex\tfilename\n4913961\t1088356\t 861512\t6863829\t 68bbd5\tvmlinux.orig\n4914025\t1088868\t 861512\t6864405\t 68be15\tvmlinux.class\n4918492\t1084612\t 861512\t6864616\t 68bee8\tvmlinux.tracepoint\n\nAgain, this patch also increases the size of the kernel, but\nlays the ground work for decreasing it.\n\n v5: Fixed net/core/drop_monitor.c to handle these updates.\n\n v4: Moved the DECLARE_TRACE() DECLARE_TRACE_NOARGS out of the\n #ifdef CONFIG_TRACE_POINTS, since the two are the same in both\n cases. The __DECLARE_TRACE() is what changes.\n Thanks to Frederic Weisbecker for pointing this out.\n\n v3: Made all register_* functions require data to be passed and\n all callbacks to take a void * parameter as its first argument.\n This makes the calling functions comply with C standards.\n\n Also added more comments to the modifications of DECLARE_TRACE().\n\n v2: Made the DECLARE_TRACE() have the ability to pass arguments\n and added a new DECLARE_TRACE_NOARGS() for tracepoints that\n do not need any arguments.\n\nAcked-by: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nAcked-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nAcked-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nCc: David S.

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.
