Hi,
This patch series enables uas support in the linux kernel. First patch
fixes usb3 streams support in xhci, patches 2-5 improve uas error
handling and patch 6 removes BROKEN from the uas kernel config.
New in v3: Fix the race pointed out by Oliver, on both existing code and
the patch.
xhci streams support is fixed, unblock usb attached scsi.

This patch adds a new list where all requests which are canceled are

urbs on bus reset (and disconnect) we'll walk over the list and clean
them up.
Without this we can end up with aborted requests lingering around in

Simplifies locking, we'll protect the list with the device spin lock.
Also plugs races which can happen when two devices operate on the
global list.
While being at it rename the list head from list to work, preparing
for the addition of a second list.

Hi.
This series enable the PPS reporting for USB serial devices (second
submission).
As opposed to the previous one this patch doesn't change the
usb_serial_handle_dcd_change interface, and only add the minimum of
code in order to enable the PPS over USB serial devices. It also add

usb_bus_list_lock is used by usbfs, but that's in the same module as
hcd.c, so there's no need to export it. Update the comment to show
that it protects the set of root hubs as well as the list of buses.
