函数名称：gen_pool_set_algo - set the allocation algorithm*@pool: pool to change allocation algorithm*@algo: custom algorithm function*@data: additional data used by @algo* Call @algo for each memory allocation in the pool

函数原型：void gen_pool_set_algo(struct gen_pool *pool, genpool_algo_t algo, void *data)

返回类型：void

参数：

类型参数名称
struct gen_pool *pool
genpool_algo_talgo
void *data
622  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
624  allocation function 等于algo
625  如果非 allocation function 则 allocation function 等于gen_pool_first_fit
628  data等于data
630  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
