Hi Philipp,

I checked 2.6.32 that dentry struct contained parent dentry struct.

Hi Jack,

Hi All,

Is possible to get parent directory's inode structure from the current inode? If so, how can I do that?

It should be possible to use the container_of macro to get the parent dentry struct. Then, you can get the parent dentry d_parent and access its inode. (Please correct me, if I'm wrong. I didn't test it).

Okay, I tried container_of, but it did not work. So I tried d_obtain_alias() which worked. But I am not sure if I have to make a call to dput() as well in order to free the dentry obtained. Anyone can confirm this? J

Philipp
