2009-02-10[SCSI] ibmvfc: Fix command timeout errorsBrian King
Currently the ibmvfc driver sets the IBMVFC_CLASS_3_ERR flag in the VFC Frame if both the adapter and the device claim support for Class 3. However, this bit actually refers to Class 3 Error Recovery, which is currently not supported by the VIOS. Setting this bit can cause lots of command timeout responses from the VIOS resulting in general instability. Fix this by never setting this bit.

2009-02-10[SCSI] sg: fix device number in blktrace dataMartin Peschke
Hi, we have run into an issue with blktrace being started for sg devices. Please apply. Thanks, Martin From: Martin Peschke <mpeschke@linux.vnet.ibm.com> The device number denoting a generic SCSI devices (sg) in a blktrace trace is broken; major and minor are always 0. It looks like sdp->device->sdev_gendev.devt is not initialized properly. The fix below uses other data to make up a valid device number, similar to the way an sg device number is generated for sysfs output.

2009-02-10[SCSI] scsi_scan: add missing interim SDEV_DEL state if slave_alloc failsJames Smart
We were running i/o and performing a bunch of hba resets in a loop. This forces a lot of target removes and then rescans. Since the resets are occuring during scan it's causing the scan i/o to timeout, invoking error recovery, etc. We end up getting some nasty crashing in scsi_scan.c due to references to old sdevs that are failing but had some lingering references that kept them around. Fix by setting device state to SDEV_DEL if the LLD's slave_alloc fails. Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2009-02-10[SCSI] ibmvscsi: Correct DMA mapping leakRobert Jennings
The ibmvscsi client driver is not unmapping the SCSI command after encountering a DMA mapping error while trying to map an indirect scattergather list for the event pool. This leads to a leak of DMA entitlement that could result in the device failing future DMA operations in a CMO environment.

2009-02-09Btrfs: don't use spin_is_contendedChris Mason
Btrfs was using spin_is_contended to see if it should drop locks before doing extent allocations during btrfs_search_slot. The idea was to avoid expensive searches in the tree unless the lock was actually contended. But, spin_is_contended is specific to the ticket spinlocks on x86, so this is causing compile errors everywhere else. In practice, the contention could easily appear some time after we started doing the extent allocation, and it makes more sense to always drop the lock instead.

But the driver doesn't clear the tx_req, which means that a next TX request (after ep_enable), might get stalled, since the driver won't queue the new reqests.

Before freeing an endpoint's muram memory, we should stop all activity of the endpoint, otherwise the QE UDC controller might do nasty things with the muram memory that isn't belong to that endpoint anymore.

2009-02-09USB: fsl_qe_udc: Fix disconnects reporting during bus resetAnton Vorontsov
Freescale QE UDC controllers can't report the "port change" states, so the only way to handle disconnects is to process bus reset interrupts. The bus reset can take some time, that is, few irqs. Gadgets may print the disconnection events, and this causes few repetitive messages in the kernel log. This patch fixes the issue by using the usb_state machine, if the usb controller has been already reset, just quit the reset irq early.

2009-02-09lockd: fix regression in lockd's handling of blocked locksJ. Bruce Fields
If a client requests a blocking lock, is denied, then requests it again, then here in nlmsvc_lock() we will call vfs_lock_file() without FL_SLEEP set, because we've already queued a block and don't need the locks code to do it again. But that means vfs_lock_file() will return -EAGAIN instead of FILE_LOCK_DENIED. So we still need to translate that -EAGAIN return into a nlm_lck_blocked error in this case, and put ourselves back on lockd's block list. The bug was introduced by bde74e4bc64415b1 "locks: add special return value for asynchronous locks".

2009-02-08radeonfb: Fix resume from D3Cold on some platformsBenjamin Herrenschmidt
For historical reason, this driver used its own saving/restoring of the PCI config space, and used the state of it on resume as an indication as to whether it needed to re-POST the chip or not. This methods breaks with the later core changes since the core will have restored things for us. This patch fixes it by removing that custom code, using standard core methods to save/restore state, and testing for the need to re-POST by comparing the content of a few key PLL registers.
