      "message": "llseek: automatically add .llseek fop\n\nAll file_operations should 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 semantic\npatch that does all this.\n\n\u003d\u003d\u003d\u003d\u003d begin semantic patch \u003d\u003d\u003d\u003d\u003d\n// This adds an llseek\u003d method to all file operations,\n// as a

      "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"

      "message": "vhost_net: a kernel-level virtio server\n\nWhat it is: vhost net is a character device that can be used to reduce\nthe number of system calls involved in virtio networking.\nExisting virtio net code is used in the guest without modification.\n\nThere\u0027s similarity with vringfd, with some differences and reduced scope\n- uses eventfd for signalling\n- structures can be moved around in memory at any time (good for\n  migration, bug work-arounds in userspace)\n- write logging is supported (good for migration)\n- support memory table and not just an offset (needed for kvm)\n\ncommon virtio related code has been put in a separate file vhost.c and\ncan be made into a separate module if/when more backends appear.  I used\nRusty\u0027s lguest.c as the source for developing this part : this supplied\nme with witty comments I wouldn\u0027t be able to write myself.\n\nWhat it is not: vhost net is not a bus, and not a generic new system\ncall. No assumptions are made on how guest performs hypercalls.\nUserspace hypervisors are supported as well as kvm.\n\nHow it works: Basically, we connect virtio frontend (configured by\nuserspace) to a backend. The backend could be a network device, or a tap\ndevice.  Backend is also configured by userspace, including vlan/mac\netc.\n\nStatus: This works for me, and I haven\u0027t see any crashes.\nCompared to userspace, people reported improved latency (as I save up to\n4 system calls per packet), as well as better bandwidth and CPU\nutilization.\n\nFeatures that I plan to look at in the future:\n- mergeable buffers\n- zero copy\n- scalability tuning: figure out the best threading model to use\n\nNote on RCU usage (this is also documented in vhost.h, near\nprivate_pointer which is the value protected by this variant of RCU):\nwhat is happening is that the rcu_dereference() is being used in a\nworkqueue item.  The role of rcu_read_lock() is taken on by the start of\nexecution of the workqueue item, of rcu_read_unlock() by the end of\nexecution of the workqueue item, and of synchronize_rcu() by\nflush_workqueue()/flush_work(). In the future we might need to apply\nsome gcc attribute or sparse annotation to the function passed to\nINIT_WORK(). Paul\u0027s ack below is for this RCU usage.\n\n(Includes fixes by Alan Cox \u003calan@linux.intel.com\u003e,\nDavid L Stevens \u003cdlstevens@us.ibm.com\u003e,\nChris Wright \u003cchrisw@redhat.com\u003e)\n\nAcked-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nAcked-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nAcked-by: \"Paul E.
