| From | Bart Van Assche <> | Subject | [PATCH 14/27] locking/lockdep: Remove a superfluous INIT_LIST_HEAD() statement | Date | Wed, 28 Nov 2018 15:43:12 -0800 |
| |
Initializing a list entry just before it is passed to list_add_tail_rcu() is not necessary because list_add_tail_rcu() overwrites the next and prev pointers anyway. Hence remove the INIT_LIST_HEAD() statement.
