Type:void

3982  limit = This limit protects against a deliberately circular list.* (Not worth introducing an rlimit for it)
3983  next_pi = next_pi
3988  If Not futex_cmpxchg_enabled Then Return
3995  If Fetch a robust-list pointer. Bit 0 signals PI futexes: Then Return
4000  If Get a simple variable from user space(futex_offset, & futex_offset) Then Return
4006  If Fetch a robust-list pointer. Bit 0 signals PI futexes: Then Return

4025  If Process a futex-list entry, check whether it's owned by the* dying task, and do notification if so: Then Return
