2011-04-29USB: add queued-unlinks test case to usbtest driverAlan Stern
This patch (as1452b) adds a new test case to the usbtest driver. Test 24 exercises the unlink-from-queue pathways in the host. It queues a user-specified number of bulk-OUT URBs of user-specified size, unlinks the fourth- and second-from-last URBs in the queue, and then waits to see if all the URBs complete in the expected way (except of course that the unlinked URBs might complete normally, if they weren't unlinked soon enough). This new test has confirmed the existence of a bug in the ehci-hcd driver, to be fixed by a separate patch.

Current renesas_usbhs was designed to save power when USB is not connected. And it assumed platform uses callback to notify connection/disconnection by external interrupt.

2011-04-29usb: renesas_usbhs: don't re-allocation pipe bufferKuninori Morimoto
Because pipe buffer allocation is very picky and difficult, current renesas_usbhs driver is not caring pipe re-allocation. In this situation, driver will create new pipe without caring old pipe if "usbhsg_ep_enable" is called after "usbhsg_ep_disable" on current driver. This mean the limited pipe and buffer will be used as waste. But it is possible to re-use same buffer to same pipe. By this patch, driver will initialize pipe when it detected new connection or new gadget, and doesn't try re-allocation for same pipe in above case.

2011-04-18Input: xen-kbdfront - fix mouse getting stuck after save/restoreIgor Mammedov
Mouse gets "stuck" after restore of PV guest but buttons are in working condition. If driver has been configured for ABS coordinates at start it will get XENKBD_TYPE_POS events and then suddenly after restore it'll start getting XENKBD_TYPE_MOTION events, that will be dropped later and they won't get into user-space. Regression was introduced by hunk 5 and 6 of 5ea5254aa0ad269cfbd2875c973ef25ab5b5e9db ("Input: xen-kbdfront - advertise either absolute or relative coordinates"). Driver on restore should ask xen for request-abs-pointer again if it is available. So restore parts that did it before 5ea5254.

2011-04-18md: fix up raid1/raid10 unplugging.NeilBrown

2011-04-18md: incorporate new plugging into raid5.NeilBrown
In raid5 plugging is used for 2 things: 1/ collecting writes that require a bitmap update 2/ collecting writes in the hope that we can create full stripes - or at least more-full. We now release these different sets of stripes when plug_cnt is zero. Also in make_request, we call mddev_check_plug to hopefully increase plug_cnt, and wake up the thread at the end if plugging wasn't achieved for some reason. Signed-off-by: NeilBrown <neilb@suse.de>
2011-04-18md: provide generic support for handling unplug callbacks.NeilBrown
When an md device adds a request to a queue, it can call mddev_check_plugged. If this succeeds then we know that the md thread will be woken up shortly, and ->plug_cnt will be non-zero until then, so some processing can be delayed. If it fails, then no unplug callback is expected and the make_request function needs to do whatever is required to make the request happen. Signed-off-by: NeilBrown <neilb@suse.de>
2011-04-18md - remove old plugging code.NeilBrown
md has some plugging infrastructure for RAID5 to use because the normal plugging infrastructure required a 'request_queue', and when called from dm, RAID5 doesn't have one of those available.

2011-04-17i2c-algo-bit: Call pre/post_xfer for bit_testAlex Deucher
Apparently some distros set i2c-algo-bit.bit_test to 1 by default. In some cases this causes i2c_bit_add_bus to fail and prevents the i2c bus from being added. In the radeon case, we fail to add the ddc i2c buses which prevents the driver from being able to detect attached monitors. The i2c bus works fine even if bit_test fails. This is likely due to gpio switching that is required and handled in the pre/post_xfer hooks, so call the pre/post_xfer hooks in the bit test as well.
