Can you supply a preprocessed source of sched.c and the options which you
compiled it with?

The only thing left from __task_rq_lock is a label.
If we look at that inlined function, we see:
static inline __attribute__((always_inline)) struct rq *__task_rq_lock(struct
task_struct *p)
{
struct rq *rq;

OK, so I'll have to find another way of using the DWARF info to see if a inline
routine, such as __task_rq_lock was used at all in the build or was just
included in the DWARF info but not referenced anywhere, have to dig more into
the available information...
BTW, if, in these cases, DW_TAG_subro
