But I agree that there is no strong reason to care\n  about inlining it.\n\n  As to the arch changes, there is only one thought I\u0027d add to the\n  record.  It was always my thinking that for an arch where\n  PTRACE_SINGLESTEP does text-modifying breakpoint insertion,\n  user_enable_single_step() should not be provided.  That is,\n  arch_has_single_step()\u003d\u003etrue means that there is an arch facility with\n  \"pure\" semantics that does not have any unexpected side effects.\n  Inserting a breakpoint might do very unexpected strange things in\n  multi-threaded situations.  Aside from that, it is a peculiar side\n  effect that user_{enable,disable}_single_step() should cause COW\n  de-sharing of text pages and so forth.  For PTRACE_SINGLESTEP, all these\n  peculiarities are the status quo ante for that arch, so having\n  arch_ptrace() itself do those is one thing.  But for building other\n  things in the future, it is nicer to have a uniform \"pure\" semantics\n  that arch-independent code can expect.\n\n  OTOH, all such arch issues are really up to the arch maintainer.  As\n  of today, there is nothing but ptrace using user_enable_single_step() et\n  al so it\u0027s a distinction without a practical difference.  If/when there\n  are other facilities that use user_enable_single_step() and might care,\n  the affected arch\u0027s can revisit the question when someone cares about\n  the quality of the arch support for said new facility.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nAcked-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\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.

      "message": "perf: Do the big rename: Performance Counters -\u003e Performance Events\n\nBye-bye Performance Counters, welcome Performance Events!\n\nIn the past few months the perfcounters subsystem has grown out its\ninitial role of counting hardware events, and has become (and is\nbecoming) a much broader generic event enumeration, reporting, logging,\nmonitoring, analysis facility.\n\nNaming its core object \u0027perf_counter\u0027 and naming the subsystem\n\u0027perfcounters\u0027 has become more and more of a misnomer. With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n  FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n  sed -i \\\n    -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n    -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n    -e \u0027s/perf_counter/perf_event/g\u0027 \\\n    -e \u0027s/nb_counters/nb_events/g\u0027 \\\n    -e \u0027s/swcounter/swevent/g\u0027 \\\n    -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n    $FILES\n\n  for N in $(find . -name perf_counter.[ch]); do\n    M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n    mv $N $M\n  done\n\n  FILES\u003d$(find . -name perf_event.*)\n\n  sed -i \\\n    -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n    -e \u0027s/COUNTER/EVENT/g\u0027 \\\n    -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n    -e \u0027s/counter/event/g\u0027 \\\n    -e \u0027s/Counter/Event/g\u0027 \\\n    $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n  with hardware registers - and these sed scripts are a bit\n  over-eager in renaming them. I\u0027ve undone some of that, but\n  in case there\u0027s something left where \u0027counter\u0027 would be\n  better than \u0027event\u0027 we can undo that on an individual basis\n  instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.
