      "message": "Enable reading page map without lock in RosAlloc::BulkFree\n\nEnabling this flag greatly reduces how much time was spent in the GC.\nIt was not done previously since it was regressing MemAllocTest. With\nthese RosAlloc changes, the benchmark score no longer regresses after\nwe enable the flag.\n\nChanged Run::AllocSlot to only have one mode of allocation. The new\nmode is finding the first free bit in the bitmap. This was\npreviously the slow path but is now the fast path. Some optimizations\nwhich enabled this include always having the alloc bitmap bits which\ncorrespond to invalid slots be set to 1. This prevents us from needing\na bound check since we will never end up allocating there.\n\nChanged revoking thread local buffer to point to an invalid run. The\ninvalid run is just a run which always has all the allocation bits set\nto 1. When a thread attempts to do a thread local allocation from here\nit will always fail and go slow path. This eliminates the need for a\nnull check for revoked runs.\n\nChanged zeroing of memory to happen during free, AllocPages should\nalways return zeroed memory. Added prefetching which happens when we\nallocate a run.\n\nSome refactoring to reduce duplicated code.\n\nErgonomics changes: Changed kStickyGcThroughputAdjustment to 1.0,\nthis helps reduce GC time.\n\nMeasurements (3 samples per benchmark):\nBefore: MemAllocTest scores: 3463, 3445, 3431\nEvaluateAndApplyChanges score | total GC time\nIter 1: 3485, 23.602436s\nIter 2: 3434, 22.499882s\nIter 3: 3483, 23.253274s\n\nAfter: MemAllocTest scores: 3495, 3417, 3409\nEvaluateAndApplyChanges score | total GC time:\nIter 1: 3375, 17.463462s\nIter 2: 3358, 16.185188s\nIter 3: 3367, 15.822312s\n\nBug: 8788501\nBug: 11790317\nBug: 9986565\nChange-Id: Ifd273a054824028dabed27c07c081dde1816f93c\n"
