ubuntu-13.10安装vmware tools报struct dentry’ has no member named ‘d_count错，修正方法

在安装vmware tools时，报错如下

/tmp/modconfig-76hAvV/vmhgfs-only/inode.c: In function ‘HgfsPermission’:
/tmp/modconfig-76hAvV/vmhgfs-only/inode.c:1893:29: error: ‘struct dentry’ has no member named ‘d_count’
          int dcount = dentry->d_count;
网上查了有许多网友遇到该问题，原因是内核版本太高，下了补丁和脚本，修复不了，于是再找相关资料研究了下

http://www.cnblogs.com/SelaSelah/archive/2013/05/05/3060671.html

以上链接问题类似，写得很好，不过修正点稍有不同

报错是在文件inode.c，解压vmware tools,在以下路径找到inode.c文件：

vmware-tools-distrib/lib/modules/source/vmhgfs-only

打开该文件，找到出错代码如下：

 

      hlist_for_each_entry(dentry,
#if LINUX_VERSION_CODE < KERNEL_VERSION(3, 9, 0)
                           p,
#endif
                           &inode->i_dentry,
                           d_alias) {
         int dcount = dentry->d_count; //这里调用d_count失败
         if (dcount) {
            LOG(4, ("Found %s %d \n", dentry->d_name.name, dcount));
            return HgfsAccessInt(dentry, mask & (MAY_READ | MAY_WRITE | MAY_EXEC));
         }

      }

     ASSERT(FALSE);

很高兴看到最后有一句ASSERT(FALSE);，表示代码不会执行到这里，那么就要在之前返回，于是乎判断dcount值!=0,

因此将int dount=dentry->d_count改为int dcount =1;当然也可以将dcount变量去掉

保存后，删除vmhgfs.tar，再执行tar -cf vmhgfs.tar vmhgfs-only生成新的vmhgfs.tar

回到vmware-tools-distrib目录，./vmware-install.pl执行vmware-install.pl大功告成！
PS:

查看了下当前内核版本：cat /proc/version

显示：Linux version 3.11.0-12-generic (buildd@allspice) (gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu7) ) #19-Ubuntu SMP Wed Oct 9 16:20:46 UTC 2013

可看到内核为:Linux version 3.11.0-12,纠心了下，非稳定版本，既然跟内核版本有关，那么下个该内核源码来确认下问题

到https://www.kernel.org/pub/linux/kernel/v3.x/下载linux 3.11.1（未找到3.11.0）

查看刚才下载的内核源码3.11.1中的inode定义如下：

struct dentry {
 /* RCU lookup touched fields */
 unsigned int d_flags;  /* protected by d_lock */
 seqcount_t d_seq;  /* per dentry seqlock */
 struct hlist_bl_node d_hash; /* lookup hash list */
 struct dentry *d_parent; /* parent directory */
 struct qstr d_name;
 struct inode *d_inode;  /* Where the name belongs to - NULL is
      * negative */
 unsigned char d_iname[DNAME_INLINE_LEN]; /* small names */

 /* Ref lookup also touches following */
 struct lockref d_lockref; /* per-dentry lock and refcount */
 const struct dentry_operations *d_op;
 struct super_block *d_sb; /* The root of the dentry tree */
 unsigned long d_time;  /* used by d_revalidate */
 void *d_fsdata;   /* fs-specific data */

 struct list_head d_lru;  /* LRU list */
 /*
  * d_child and d_rcu can share memory
  */
 union {
  struct list_head d_child; /* child of parent list */
   struct rcu_head d_rcu;
 } d_u;
 struct list_head d_subdirs; /* our children */
 struct hlist_node d_alias; /* inode alias list */
};

该结构体确实没有d_count,于是报错

 以上不妥之处，欢迎朋友们斧正
