    usb-storage: Fix devices that cannot handle 32k transfers · 33abc04f
    Doug Maxey 提交于
    When a device cannot handle the smallest previously limited transfer
    size (64 blocks) without stalling, limit the device to the amount of
    packets that fit in a platform native page.
    
    The lowest possible limit is PAGE_CACHE_SIZE, so if the device is ever
    used on a platform that has larger than 8K pages, you lose unless you
    can convince the device firmware folks to fix the issue.
