This includes three minor fixes, mostly due to cut-and-paste issues.

Browse Source 
The first is a cut and paste issue that changed the amount of stack
 to skip when tracing a stack dump from 0 to 6, which basically made
 the stack disappear for small stack traces.
 
 The second fix is just removing an unused field in a struct that is no
 longer used, and currently just wastes space.
 
 The third is another cut-and-paste fix that had a tracepoint recording
 the wrong field (it was recording the previous field a second time).
