Steven Rostedt f37c3bbc63 tracing: Add ustring operation to filtering string pointers
Since referencing user space pointers is special, if the user wants to
filter on a field that is a pointer to user space, then they need to
specify it.

Add a ".ustring" attribute to the field name for filters to state that the
field is pointing to user space such that the kernel can take the
appropriate action to read that pointer.

Fixes: 77360f9bbc ("tracing: Add test for user space strings when filtering on string pointers")
