Date: Wed, 1 Nov 2017 22:26:25 +0100 From: Willy Tarreau <w@....eu> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, linux@...ck-us.net Cc: Chris Brandt <chris.brandt@...esas.com>, Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Willy Tarreau <w@....eu> Subject: [PATCH 3.10 100/139] usb: r8a66597-hcd: decrease timeout From: Chris Brandt <chris.brandt@...esas.com> commit dd14a3e9b92ac6f0918054f9e3477438760a4fa6 upstream. The timeout for BULK packets was 300ms which is a long time if other endpoints or devices are waiting for their turn. Changing it to 50ms greatly increased the overall performance for multi-endpoint devices.
