    NFS: Fix a race in sillyrename · 565277f6
    Trond Myklebust authored
    lookup() and sillyrename() can race one another because the sillyrename()
    completion cannot take the parent directory's inode->i_mutex since the
    latter may be held by whoever is calling dput().
    We therefore have little option but to add extra locking to ensure that
    nfs_lookup() and nfs_atomic_open() do not race with the sillyrename
    If somebody has looked up the sillyrenamed file in the meantime, we just
    transfer the sillydelete information to the new dentry.
