Hi List,
I noticed that there are just few functions suffixed with rcu for
rculist. And from the source of Linux kernel rculist, I came up with
some comments saying that list_empty_rcu() can be simply achieved by
calling list_empty(). Is this true to urcu too? My questions is, are
following equivalents true?
list_empty_rcu -> list_empty
Yes.
list_del_init_rcu -> list_del_init
No.
Add a trivial comment.
There is no list_del_init_rcu(), "init" hurts "rcu".
If you need a re-initialized object after deletion, you should use
synchronzie_rcu():
list_del_rcu();
synchronize_rcu();
CDS_INIT_LIST_HEAD();
If there are more equivalents, please show light on it.
I will prepare a patch to extend and document the list and rculist APIs.
Your feedback is welcome.
Thanks!
Mathieu
Thanks,
