返回类型：int

参数：

类型参数名称
struct ctl_table *table
intwrite
void __user *buffer
size_t *lenp
loff_t *ppos
2612  tmptaint等于get_taint()
2615  如果write且非操作权限检查则返回:负EPERM
2618  t等于table
2619  data等于tmptaint
2620  err等于指定大小读sysctl长整数向量
2621  如果err小于0则返回:err
2624  如果write则
2630  以i小于BITS_PER_LONG且tmptaint右移i位循环
2631  如果tmptaint右移i位按位与1则add_taint: add a taint flag if not already set.*@flag: one of the TAINT_* constants.*@lockdep_ok: whether lock debugging is still OK.* If something bad has gone wrong, you'll want @lockdebug_ok = false, but for
2636  返回:err
