      "message": "Implement pthread_attr_getinheritsched/pthread_attr_setinheritsched.\n\nHistorically, Android defaulted to EXPLICIT but with a special case\nbecause SCHED_NORMAL/priority 0 was awkward. Because the code couldn\u0027t\nactually tell whether SCHED_NORMAL/priority 0 was a genuine attempt to\nexplicitly set those attributes (because the parent thread is SCHED_FIFO,\nsay) or just because the pthread_attr_t was left at its defaults.\n\nNow we support INHERIT, we could call sched_getscheduler to see whether\nwe actually need to call sched_setscheduler, but since the major cost\nis the fixed syscall overhead, we may as well just conservatively\ncall sched_setscheduler and let the kernel decide whether it\u0027s a\nno-op. (Especially because we\u0027d then have to add both sched_getscheduler\nand sched_setscheduler to any seccomp filter.)\n\nPlatform code (or app code that only needs to support \u003e\u003d P) can actually\nadd a call to pthread_attr_setinheritsched to say that they just want\nto inherit (if they know that none of their threads actually mess with\nscheduler attributes at all), which will save them a sched_setscheduler\ncall except in the doubly-special case of SCHED_RESET_ON_FORK (which we\ndo handle).\n\nAn alternative would be \"make pthread_attr_setschedparams and\npthread_attr_setschedprio set EXPLICIT and change the platform default\nto INHERIT\", but even though I can only think of weird pathological\nexamples where anyone would notice that change, that behavior -- of\npthread_attr_setschedparams/pthread_attr_setschedprio overriding an\nearlier call to pthread_attr_setinheritsched -- isn\u0027t allowed by POSIX\n(whereas defaulting to EXPLICIT is).\n\nIf we have a lot of trouble with this change in the app compatibility\ntesting phase, though, we\u0027ll want to reconsider this decision!\n\n -*-\n\nThis change also removes a comment about setting the scheduler attributes\nin main_thread because we\u0027d have to actually keep them up to date,\nand it\u0027s not clear that doing so would be worth the trouble.\n\nAlso make async_safe_format_log preserve errno so we don\u0027t have to be\nso careful around it.\n\nBug: http://b/67471710\nTest: ran tests\nChange-Id: Idd026c4ce78a536656adcb57aa2e7b2c616eeddf\n"

      "message": "Use clang\u0027s nullability instead of nonnull.\n\nhttp://clang.llvm.org/docs/AttributeReference.html#nonnull\n\n_Nonnull is similar to the nonnull attribute in that it will instruct\ncompilers to warn the user if it can prove that a null argument is\nbeing passed. Unlike the nonnull attribute, this annotation indicated\nthat a value *should not* be null, not that it *cannot* be null, or\neven that the behavior is undefined. The important distinction is that\nthe optimizer will perform surprising optimizations like the\nfollowing:\n\n    void foo(void*) __attribute__(nonnull, 1);\n\n    int bar(int* p) {\n      foo(p);\n\n      // The following null check will be elided because nonnull\n      // attribute means that, since we call foo with p, p can be\n      // assumed to not be null. Thus this will crash if we are called\n      // with a null pointer.\n      if (src !\u003d NULL) {\n        return *p;\n      }\n      return 0;\n    }\n\n    int main() {\n      return bar(NULL);\n    }\n\nNote that by doing this we are no longer attaching any sort of\nattribute for GCC (GCC doesn\u0027t support attaching nonnull directly to a\nparameter, only to the function and naming the arguments\npositionally). This means we won\u0027t be getting a warning for this case\nfrom GCC any more. People that listen to warnings tend to use clang\nanyway, and we\u0027re quickly moving toward that as the default, so this\nseems to be an acceptable tradeoff.\n\nChange-Id: Ie05fe7cec2f19a082c1defb303f82bcf9241b88d\n"

So I make following changes in this CL:\n\n1. Add pending flags in rwlock.state, so we don\u0027t need to synchronize\nbetween different atomic variables. Using compare_and_swap operations\non rwlock.state is enough for all state change.\n\n2. Add pending_lock to protect readers/writers waiting and wake up\noperations.
