anon_inode_getfile

函数名称：anon_inode_getfile - creates a new file instance by hooking it up to an* anonymous inode, and a dentry that describe the "class"* of the file*@name: [in] name of the "class" of the new file*@fops: [in] file operations for the new file*@priv: [in] private

函数原型：struct file *anon_inode_getfile(const char *name, const struct file_operations *fops, void *priv, int flags)

返回类型：struct file

参数：

类型	参数	名称
const char *	name
const struct file_operations *	fops
void *	priv
int	flags

如果是错误则返回:错误号

如果owner且非判断模块是否处于活动状态则返回:错误号

get additional reference to inode; caller must already hold one.

file等于alloc_file_pseudo(anon_inode_inode, anon_inode_mnt, name, flags & (O_ACCMODE | O_NONBLOCK), fops)

如果是错误则转到:err

f_mapping等于i_mapping

needed for tty driver, and maybe others 等于priv
