* xfs: reject swapext ioctl on swapfilesChristoph Hellwig2009-02-121-0/+6
| | | | | | | | | Swapfiles are magic - I/O is directly initialized by the VM without involving the filesystem. Swapping out extents underneath the VM thus can cause severe problems. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Felix Blyakher <felixb@sgi.com>

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.

| | * | PCI PM: make the PM core more careful with drivers using the new PM frameworkRafael J. Wysocki2009-02-041-52/+93

In particular, it attempts to disable the devices (which is unnecessary), to save their state (which may be undesirable if the driver has done that already) and to put them into low power states (again, this may be undesirable if the driver has already put the device into a low power state). That need not be the right thing to do, so make the core be more careful in this respect. Generally, there are the following categories of devices to consider: * bridge devices without drivers * non-bridge devices without drivers * bridge devices with drivers * non-bridge devices with drivers and each of them should be handled differently. For bridge devices without drivers the PCI PM core will save their state on suspend and restore it (early) during resume, after putting them into D0 if necessary. It will not attempt to do anything else to these devices. For non-bridge devices without drivers the PCI PM core will disable them and save their state on suspend. During resume, it will put them into D0, if necessary, restore their state (early) and reenable them. For bridge devices with drivers the PCI PM core will only save their state on suspend if the driver hasn't done that already. Still, the core will restore their state (early) during resume, after putting them into D0, if necessary. For non-bridge devices with drivers the PCI PM core will only save their state on suspend if the driver hasn't done that already. Also, if the state of the device hasn't been saved by the driver, the core will attempt to put the device into a low power state. During resume the core will restore the state of the device (early), after putting it into D0, if necessary. Signed-off-by: Rafael J.

We determine this by checking to see if the parent's device list is completely empty. Unfortunately, we never hit that code because the parent is considered an upstream port, and never had an ASPM link_state associated with it. The early check for !link_state causes us to return early, we never discover that our device list is empty, and thus we never remove the downstream ports' link_state nodes. Instead of checking to see if the parent's device list is empty, we can check to see if we are the last device on the list, and if so, then we know that we can clean up properly.
