Subject: [PATCH 0/2] xhci, usbnet: fixes for 3.14
Date: Fri, 7 Mar 2014 17:06:56 +0200 [thread overview]
Message-ID: <1394204818-25323-1-git-send-email-mathias.nyman@linux.intel.com> (raw)
Hi Greg,
These two xhci scatter-gather related patches should be reverted to avoid
USB 3.0 mass storage regression for users.
Sarah and Alan concluded that this the best choice until proper TD fragmentation
rules are implemented, discussion is here:
http://marc.info/?l=linux-usb&m=139395884021971&w=2
The patch xhci 1.0: "Limit arbitrarily-aligned scatter gather." was added
to 3.14-rc1 and stable, both patches should be reverted from stable and 3.14
A few mass storage regression cases:
