Subject: [PATCH v5 2/2] uas: bump hw_max_sectors to 2048 blocks for SS or faster drives
Date: Thu, 3 Sep 2020 16:50:35 +0800 [thread overview]
Message-ID: <20200903085035.307720-2-tom.ty89@gmail.com> (raw)
In-Reply-To: <20200903085035.307720-1-tom.ty89@gmail.com>
There's no reason for uas to use a smaller value of max_sectors than
usb-storage.
