Hello Al Viro, I have a question about spin_unlock(dentry) after lock_parent(dentry). In lock_parent(dentry), spin_unlock(dentry) is called. And spin_lock(dentry) is called again when (parent != dentry) is true. Otherwise, dentry left spin_unlock-ed and lock_parent() returns NULL. Even in the case of lock_parent() returns NULL, shrink_dentry_list() calls spin_unlock(dentry). Is it balanced and correct? J. R.
