    Subject[PATCH 4.14 162/267] USB: uas: heed CAPACITY_HEURISTICS
    Date
    From: Oliver Neukum <oneukum@suse.com>

    commit 335cbbd5762d5e5c67a8ddd6e6362c2aa42a328f upstream.

    There is no need to ignore this flag. We should be as close
    to storage in that regard as makes sense, so honor flags whose
    cost is tiny.
