| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After 2.6.24 there was a plan to make the PM core acquire all device semaphores during a suspend/hibernation to protect itself from concurrent operations involving device objects. That proved to be too heavy-handed and we found a better way to achieve the goal, but before it happened, we had introduced the functions device_pm_schedule_removal() and destroy_suspended_device() to allow drivers to "safely" destroy a suspended device and we had adapted some drivers to use them. Now that these functions are no longer necessary, it seems reasonable to remove them and modify their users to use the normal device unregistration instead. Signed-off-by: Rafael J.

Otherwise remote wakeup won't always be configurable for runtime power management. This patch (as1056b) fixes the oversight. David Brownell adds: More accurately, fixes the "regression" ... as noted sometime last summer, after 296699de6bdc717189a331ab6bbe90e05c94db06 introduced CONFIG_SUSPEND.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the PM core to protect its data structures, specifically the dpm_active list, from being corrupted if a child of the currently suspending device is registered concurrently with its ->suspend() callback. In that case, since the new device (the child) is added to dpm_active after its parent, the PM core will attempt to suspend it after the parent, which is wrong. Introduce a new member of struct dev_pm_info, called 'sleeping', and use it to check if the parent of the device being added to dpm_active has been suspended, in which case the device registration fails. Also, use 'sleeping' for checking if the ordering of devices on dpm_active is correct. Introduce variable 'all_sleeping' that will be set to 'true' once all devices have been suspended and make new device registrations fail until 'all_sleeping' is reset to 'false', in order to avoid having unsuspended devices around while the system is going into a sleep state. Remove pm_sleep_rwsem which is not necessary any more. Special thanks to Alan Stern for discussions and suggestions that lead to the creation of this patch. Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've just found how easy it is to accidentally register a sysdev_driver for two different classes. When this happens, bad things happen as the sysdev_driver structure keeps has the list entry for the driver registration.

* [SCSI] transport_class: BUG if we can't release the attribute containerJames Bottomley2008-04-07
| | | | | | | | | | | | | | | | | | | Every current transport class calls transport_container_release but ignores the return value. This is catastrophic if it returns an error because the containers are part of a global list and the next action of almost every transport class is to free the memory used by the container. Fix this by making transport_container_release a void, but making it BUG if attribute_container_release returns an error ... this catches the root cause of a system panic much earlier. If we don't do this, we get an eventual BUG when the attribute container list notices the corruption caused by the freed memory it's still referencing. Also made attribute_container_release __must_check as a reminder. Cc: Greg KH <greg@kroah.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* driver core: fix small mem leak in driver_add_kobj()Jesper Juhl2008-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Coverity checker spotted that we leak the storage allocated to 'name' in int driver_add_kobj(). The leak looks legit to me - this is the code : int driver_add_kobj(struct device_driver *drv, struct kobject *kobj, const char *fmt, ...) { va_list args; char *name; int ret; va_start(args, fmt); name = kvasprintf(GFP_KERNEL, fmt, args); ^^^^^^^^ This dynamically allocates space... va_end(args); if (!name) return -ENOMEM; return kobject_add(kobj, &drv->p->kobj, "%s", name); ^^^^^^^^ This neglects to free the space allocated } Inside kobject_add() a copy of 'name' will be made and used. As far as I can see, Coverity is correct in flagging this as a leak, but I'd like some configmation before the patch is applied. This should fix it.

| | | | | | | | | | | | | | | | | There's a bug in the current implementation of dma_get_required_mask() where it ands the returned mask with the current device mask. This rather defeats the purpose if you're using the call to determine what your mask should be (since you will at that time have the default DMA_32BIT_MASK). This bug results in any driver that uses this function *always* getting a 32 bit mask, which is wrong. Fix by removing the and with dev->dma_mask.

| | | | | | | | | | | | | | | | | | | | | | | | | | Driver core: Remove unneeded get_{device,driver}() calls. Code trying to add/remove attributes must hold a reference to the device resp. driver anyway, so let's remove those reference count games.

* | PM: Make PM_TRACE more architecture independentJohannes Berg2008-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When trying to debug a suspend failure I started implementing PM_TRACE for powerpc. I then noticed that I'm debugging a suspend failure and so PM_TRACE isn't useful at all, but thought that nonetheless this could be useful in the future. Basically, to support PM_TRACE, you add a Kconfig option that selects PM_TRACE and provides the infrastructure as per the help text of PM_TRACE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver core, and some other parts of the kernel just want to find a device based on a name for a specific bus. Give them a simple wrapper to prevent them from having to always roll their own. This will be used in the PPC patch later in this series.
