      "message": "atomic: add atomic_inc_not_zero_hint()\n\nFollowup of perf tools session in Netfilter WorkShop 2010\n\nIn the network stack we make high usage of atomic_inc_not_zero() in\ncontexts we know the probable value of atomic before increment (2 for udp\nsockets for example)\n\nUsing a special version of atomic_inc_not_zero() giving this hint can help\nprocessor to use less bus transactions.\n\nOn x86 (MESI protocol) for example, this avoids entering Shared state,\nbecause \"lock cmpxchg\" issues an RFO (Read For Ownership)\n\nakpm: Adds a new include/linux/atomic.h.  This means that new code should\nhenceforth include linux/atomic.h and not asm/atomic.h.  The presence of\ninclude/linux/atomic.h will in fact cause checkpatch.pl to warn about use\nof asm/atomic.h.  The new include/linux/atomic.h becomes the place where\narch-neutral atomic_t code should be placed.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nCc: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@infradead.org\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: \"Paul E.
