no, it's the call's return address that is work_resched+6.

to get a more usable snapshot of what this task is doing you'd need
something like SysRq-P output. (that works on PREEMPT_RT only if you
enable /proc/sys/kernel/debug_direct_keyboard - but careful, it might
break if you generate too many interrupts - i usually only to do the
SysRq-P and hope that it doesnt break then.)
