[DTrace-devel] [PATCH 1/3] String constants should be marked as DT_NF_DPTR

[Kris Van Hees]

Although string constants are represented using a scalar offset into the
string constant table, the generated BPF code uses actual pointers into
the string constant table.  They are therefore pointers to DTrace-managed
storage (DT_NF_DPTR).
