Subject: changing d_parent
Date: Sun, 18 May 2003 19:42:29 +0200 [thread overview]
Message-ID: <3EC7C605.DB4BA3ED@free.fr> (raw)
I would like to change the "d_parent" field of a dentry. This is for
shrinking entry equivalent to a "./" in my filesystem namespace.
The dentry has just been allocated and has no child. I'm new to the
dcache and i would like to know if thoses lines are is safe:
spin_lock(&dcache_lock);
list_del(&dentry->d_child);
dput(dentry->d_parent);
dentry->d_parent = dget(newparent);
list_add(&dentry->d_child, &newparent->d_subdirs);
spin_unlock(&dcache_lock);
kind regards,
j.
