类型参数名称
struct super_block *sb
const struct inode *dir
umode_tmode
dev_tdev
66  inode等于取新的索引节点
68  如果inode则
69  Stat data, not accessed from path walking 等于get_next_ino()
70  de_init_owner - Init uid,gid,mode for new inode according to posix standards*@inode: New inode*@dir: Directory inode*@mode: mode of the new inode
71  a_ops等于ramfs_aops
72  This is non-atomic. Only to be used before the mapping is activated.* Probably needs a barrier...
73  mapping_set_unevictable(i_mapping)
74  i_atime等于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.
76  默认
77  init_special_inode(inode, mode, dev)
78  退出
79  当: & == S_IFREG
80  i_op等于rnal.h: ramfs internal definitions* Copyright (C) 2005 Red Hat, Inc. All Rights Reserved.* Written by David Howells (dhowells@redhat.com)
81  rmer ->i_op->default_file_ops 等于ramfs_file_operations
82  退出
83  当: & == S_IFDIR
84  i_op等于ramfs_dir_inode_operations
85  rmer ->i_op->default_file_ops 等于simple_dir_operations
88  _nlink - directly increment an inode's link count*@inode: inode* This is a low-level filesystem helper to replace any* direct filesystem manipulation of i_nlink. Currently,* it is only here for parity with dec_nlink().
89  退出
90  当: & == S_IFLNK
91  i_op等于page_symlink_inode_operations
92  inode_nohighmem(inode)
