函数名称：ramfs_symlink

函数原型：static int ramfs_symlink(struct inode *dir, struct dentry *dentry, const char *symname)

返回类型：int

参数：

类型参数名称
struct inode *dir
struct dentry *dentry
const char *symname
134  error等于负ENOSPC
136  inode等于ramfs_get_inode(i_sb, dir, S_IFLNK | S_IRWXUGO, 0)
137  如果inode则
138  l等于strlen - Find the length of a string*@s: The string to be sized加1
139  error等于page_symlink(inode, symname, l)
140  如果非error则
141  为目录项建立索引
142  获得目录项引用
143  i_mtime等于i_ctime等于rrent_time - Return FS time*@inode: inode.* Return the current time truncated to the time granularity supported by* the fs.* Note that inode and inode->sb cannot be NULL.* Otherwise, the function warns and returns time without truncation.
144  否则放置一个索引节点
147  返回:error
