返回类型:ssize_t
参数:
类型 | 参数 | 名称 |
---|---|---|
struct file * | file | |
const char __user * | user_buf | |
size_t | count | |
loff_t * | ppos |
96 | 如果s or device private pointer 不等于LOCKEVENT_reset_cnts则返回:count |
101 | ptr等于per_cpu_ptr(Per-cpu counts, cpu) |
103 | 以i小于 # of write lock handoffs 循环WRITE_ONCE(ptr[i], 0) |
106 | 返回:count |
