init_srcu_struct_fields

Name:Initialize non-compile-time initialized fields, including the* associated srcu_node and srcu_data structures. The is_static* parameter is passed through to init_srcu_struct_nodes(), and* also tells us that ->sda has already been wired up to srcu_data.

Proto:static int init_srcu_struct_fields(struct srcu_struct *ssp, bool is_static)

Type:int

Parameter:

Initialize SRCU combining tree. Note that statically allocated* srcu_struct structures might already have srcu_read_lock() and* srcu_read_unlock() running against them. So if the is_static parameter

Return If sda Then 0 Else -ENOMEM
