    Subject[PATCH v2 3/4] erofs: relinquish volume with mutex held
    Date
    Relinquish fscache volume with mutex held.  Otherwise if a new domain is
    registered when the old domain with the same name gets removed from the
    list but not relinquished yet, fscache may complain the collision.
