value given to single_open() can be found in the private field of the seq_file structure. When using single_open(), the programmer should use single_release() instead of seq_release() in the file_operations structure to avoid a memory leak. 根据以上这段说明,在mytest_proc_open函数中,只...
static const struct file_operations md_seq_fops = { .owner = THIS_MODULE, .open = md_seq_open, .read = seq_read, .llseek = seq_lseek, .release = seq_release_private, .poll = mdstat_poll, }; 只是md还多赋值了一个poll成员。 无本质差异。
