staging: lustre: lnet: conrpc: Use list_for_each_entry_safe
Doubly linked lists which are iterated using list_empty and list_entry macros have been replaced with list_for_each_entry_safe macro. This makes the iteration simpler and more readable. This patch replaces the while loop containing list_empty and list_entry with list_for_each_entry_safe. This was done with Coccinelle. @@ expression E1; identifier I1, I2; type T; iterator name list_for_each_entry_safe; @@ T *I1; + T *tmp; ... - while (list_empty(&E1) == 0) + list_for_each_entry_safe (I1, tmp, &E1, I2) { ...when != T *I1; - I1 = list_entry(E1.next, T, I2); ... } Signed-off-by: Bhaktipriya Shridhar <bhaktipriya96@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
