$ tools/perf/trace/beauty/sync_file_range.sh
static const char *sync_file_range_flags[] = {
[ilog2(1) + 1] = "WAIT_BEFORE",
[ilog2(2) + 1] = "WRITE",
[ilog2(4) + 1] = "WAIT_AFTER",
};

When all are the above are present, then we have something called
SYNC_FILE_RANGE_WRITE_AND_WAIT, that will be special cased in the
upcoming scnprintf beautifier for this flags arg.
