类型参数名称
struct file *file
int (*show
void *data
size_tsize
590  buf等于seq_buf_alloc(size)
592  如果非buf则返回:负ENOMEM
594  ret等于single_open(file, show, data)
595  如果ret则
596  kvfree() - Free memory.*@addr: Pointer to allocated memory.* kvfree frees memory allocated by any of vmalloc(), kmalloc() or kvmalloc().* It is slightly more efficient to use kfree() or vfree() if you are certain* that you know which one to use.
597  返回:ret
599  buf等于buf
600  size等于size
601  返回:0
