  "message": "[roll] Roll fuchsia [starnix][tracing] TraceMarkerFile: fix write() return value\n\nIn some cases, `TraceMarkerFile::write()` needs to truncate\nthe data sent by the writer.\n\nHowever, in such cases, the function should still tell the\nwriter that all the bytes were written.\n\nOtherwise, for example, the writer might retry.\n\nTest: manual (see below)\n\nManual test\n-----------\nsorrel:/sys/kernel/tracing # echo 1 \u003e tracing_on\nsorrel:/sys/kernel/tracing # cat tracing_on\n1\nsorrel:/sys/kernel/tracing # echo \u0027hello world\u0027 \u003e trace_marker\nsorrel:/sys/kernel/tracing #\n\nPreviously, the `echo` command would hang. Or, more specifically,\nthe `echo` command would sit in a tight loop, trying to write\nout the last byte.\n\nOriginal-Reviewed-on: https://fuchsia-review.googlesource.com/c/fuchsia/+/1445906\nOriginal-Revision: 1d655109dd3f817bec59ecf3392c5672f524f1ed\nGitOrigin-RevId: 79e467d706d589a05936be4c9102376fdec507fa\nChange-Id: I73f943c30d987f2d1e4e2946ab30155e554b8659\n",
