When I run crash on a recent rawhide x86_64 kernel, I seem to be
getting this error:
crash: invalid structure member offset: task_struct_parent
FILE: task.c LINE: 2163 FUNCTION: store_context()

Relevant package versions:

...machine is a x86_64 FV xen guest. Any thoughts?
Thanks,
Hmmm. The task_struct.parent member still exists upstream with
the same name, shown here after a fresh git pull:
/*
* pointers to (original) parent process, youngest child, younger sibling,
* older sibling, respectively. (p->father can be replaced with
* p->parent->pid)
*/
struct task_struct *real_parent; /* real parent process (when being debugged) */
struct task_struct *parent; /* parent process */
If you run "gdb vmlinux" and then do a "ptype struct task_struct",
does
it not show the parent member?
