Re: 答复: parent inode from the current struct inode

Hi Jack,

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?

since d_obtain_alias() calls dput when something goes wrong after
allocating the dentry, I'm assuming that you also have to call dput to
free the dentry.
