warn_on_bintable

函数名称：Print each legacy sysctl (approximately) only once.* To avoid making the tables non-const use a external* hash-table instead.* Worst case hash collision: 6, but very rarely.* NOTE! We don't use the SMP-safe bit tests. We simply* don't care enough.

函数原型：static void warn_on_bintable(const int *name, int nlen)

返回类型：void

参数：

类型	参数	名称
const int *	name
int	nlen

hash等于FNV32_OFFSET

以i小于nlen 循环 hash等于hash按位异或name[i]的值乘FNV32_PRIME

hash取模等于WARN_ONCE_HASH_SIZE

如果__test_and_set_bit - Set a bit and return its old value*@nr: Bit to set*@addr: Address to count from* This operation is non-atomic. If two instances of this operation race, one* can appear to succeed but actually fail.则返回

deprecated_sysctl_warning(name, nlen)
