函数名称：hashtable_shrink - Shrink hash table while allowing concurrent lookups*@ht: the hash table to shrink* This function shrinks the hash table to fit, i

函数原型：static int rhashtable_shrink(struct rhashtable *ht)

返回类型：int

参数：

类型参数名称
struct rhashtable *ht>mutex.
380  old_tbl等于rht_dereference(tbl, >mutex.)
381  nelems等于atomic_read( & nelems)
382  size等于0
384  如果nelems则size等于undup_pow_of_two - round the given value up to nearest power of two*@n: parameter* round the given value up to the nearest power of two* - the result is undefined when n == 0* - this can be used to initialise global variables from constant data(nelems * 3 / 2)
386  如果size小于min_size则size等于min_size
389  如果size小于等于size则返回:0
392  如果rht_dereference(future_tbl, >mutex.)则返回:负EEXIST
395  返回:rhashtable_rehash_alloc(>mutex., old_tbl, size)
