    NFSv4.1: Fix a protocol issue with CLOSE stateids · 4a1e2feb
    Trond Myklebust 提交于
    According to RFC5661 Section 18.2.4, CLOSE is supposed to return
    the zero stateid. This means that nfs_clear_open_stateid_locked()
    cannot assume that the result stateid will always match the 'other'
    field of the existing open stateid when trying to determine a race
    with a parallel OPEN.
    
    Instead, we look at the argument, and check for matches.
