futex: documentation: fix inconsistent description of futex list_op_p…
…ending Strictly speaking list_op_pending points to the 'lock entry', not the 'lock word' (which is actually at 'offset' from 'lock entry'). We can infer this based on reading the code in kernel/futex.c: struct robust_list __user *entry, *next_entry, *pending; ... if (fetch_robust_entry(&pending, &head->list_op_pending, &pip)) return; ... if (pending) handle_futex_death((void __user *)pending + futex_offset, curr, pip); Which is also consistent with the rest of the docs on robust futex lists.
