[PATCH] fuse: fix dereferencing dentry parent
There's no locking for ->d_revalidate, so fuse_dentry_revalidate() should use
dget_parent() instead of simply dereferencing ->d_parent.
Due to topology changes in the directory tree the parent could become negative
or be destroyed while being used. There hasn't been any reports about this
yet.
