+// CovMetaBlob is a container for holding the meta-data symbol (an
+// RODATA variable) for an instrumented Go package. Here "p" points to
+// the symbol itself, "len" is the length of the sym in bytes, and
+// "hash" is an md5sum for the sym computed by the compiler. When
+// the init function for a coverage-instrumented package executes, it
+// will make a call into the runtime which will create a covMetaBlob
+// object for the package and chain it onto a global list.
