      "message": "NBLog: Make separate readers for dumping logs and histograms\n\nPrior to this commit, the dumping of log contents and histograms from\nPerformanceAnalysis were in conflict because histograms obtained data\nfrom the merger\u0027s buffer, and the merger used the same readers as the\nlog dumps. One read would consume the whole buffer, which would cause\neither a lossy dump or an lossy merge. Now, both operations can exist\nwithout loss of information from sharing the same reader.\n\nThe step of merging contents of each writer\u0027s local buffer into a bigger\nbuffer has effectively been removed. PerformanceAnalysis now directly\nreads from each writer\u0027s buffer instead of reading from the merger\u0027s\nbigger buffer.\n\nTest: dumpsys media.log -r\nBug: 68148948\nChange-Id: I6d8ea6a8f6a43555183a6d8f17af567506a102f1\n"
