      "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": "net: Generalize socket rx gap / receive queue overflow cmsg\n\nCreate a new socket level option to report number of queue overflows\n\nRecently I augmented the AF_PACKET protocol to report the number of frames lost\non the socket receive queue between any two enqueued frames.  This value was\nexported via a SOL_PACKET level cmsg.  AFter I completed that work it was\nrequested that this feature be generalized so that any datagram oriented socket\ncould make use of this option.  As such I\u0027ve created this patch, It creates a\nnew SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a\nSOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue\noverflowed between any two given frames.  It also augments the AF_PACKET\nprotocol to take advantage of this new feature (as it previously did not touch\nsk-\u003esk_drops, which this patch uses to record the overflow count).  Tested\nsuccessfully by me.\n\nNotes:\n\n1) Unlike my previous patch, this patch simply records the sk_drops value, which\nis not a number of drops between packets, but rather a total number of drops.\nDeltas must be computed in user space.\n\n2) While this patch currently works with datagram oriented protocols, it will\nalso be accepted by non-datagram oriented protocols. I\u0027m not sure if thats\nagreeable to everyone, but my argument in favor of doing so is that, for those\nprotocols which aren\u0027t applicable to this option, sk_drops will always be zero,\nand reporting no drops on a receive queue that isn\u0027t used for those\nnon-participating protocols seems reasonable to me.  This also saves us having\nto code in a per-protocol opt in mechanism.\n\n3) This applies cleanly to net-next assuming that commit\n977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted\n\nSigned-off-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: David S.

Each iteration has to use at least 2 cache\nlines.\n\nThis can be problematic if some chains are very long.\n\n2) The goal\n-----------\n\nThe idea I had is to change things so that INET_MATCH() may return\nFALSE in 99% of cases only using the data already in the CPU cache,\nusing one cache line per iteration.\n\n3) Description of the patch\n---------------------------\n\nAdds a new \u0027unsigned int skc_hash\u0027 field in \u0027struct sock_common\u0027,\nfilling a 32 bits hole on 64 bits platform.\n\nstruct sock_common {\n\tunsigned short\t\tskc_family;\n\tvolatile unsigned char\tskc_state;\n\tunsigned char\t\tskc_reuse;\n\tint\t\t\tskc_bound_dev_if;\n\tstruct hlist_node\tskc_node;\n\tstruct hlist_node\tskc_bind_node;\n\tatomic_t\t\tskc_refcnt;\n+\tunsigned int\t\tskc_hash;\n\tstruct proto\t\t*skc_prot;\n};\n\nStore in this 32 bits field the full hash, not masked by (ehash_size -\n1) Using this full hash as the first comparison done in INET_MATCH\npermits us immediatly skip the element without touching a second cache\nline in case of a miss.\n\nSuppress the sk_hashent/tw_hashent fields since skc_hash (aliased to\nsk_hash and tw_hash) already contains the slot number if we mask with\n(ehash_size - 1)\n\nFile include/net/inet_hashtables.h\n\n64 bits platforms :\n#define INET_MATCH(__sk, __hash, __cookie, __saddr, __daddr, __ports, __dif)\\\n     (((__sk)-\u003esk_hash \u003d\u003d (__hash))\n     ((*((__u64 *)\u0026(inet_sk(__sk)-\u003edaddr)))\u003d\u003d (__cookie))   \u0026\u0026  \\\n     ((*((__u32 *)\u0026(inet_sk(__sk)-\u003edport))) \u003d\u003d (__ports))   \u0026\u0026  \\\n     (!((__sk)-\u003esk_bound_dev_if) || ((__sk)-\u003esk_bound_dev_if \u003d\u003d (__dif))))\n\n32bits platforms:\n#define TCP_IPV4_MATCH(__sk, __hash, __cookie, __saddr, __daddr, __ports, __dif)\\\n     (((__sk)-\u003esk_hash \u003d\u003d (__hash))                 \u0026\u0026  \\\n     (inet_sk(__sk)-\u003edaddr          \u003d\u003d (__saddr))   \u0026\u0026  \\\n     (inet_sk(__sk)-\u003ercv_saddr      \u003d\u003d (__daddr))   \u0026\u0026  \\\n     (!((__sk)-\u003esk_bound_dev_if) || ((__sk)-\u003esk_bound_dev_if \u003d\u003d (__dif))))\n\n\n- Adds a prefetch(head-\u003echain.first) in \n__inet_lookup_established()/__tcp_v4_check_established() and \n__inet6_lookup_established()/__tcp_v6_check_established() and \n__dccp_v4_check_established() to bring into cache the first element of the \nlist, before the {read|write}_lock(\u0026head-\u003elock);\n\nSigned-off-by: Eric Dumazet \u003cdada1@cosmosbay.com\u003e\nAcked-by: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\nSigned-off-by: David S.
