Everybody wants to pass it a function pointer, and in fact, that is what
you _must_ pass it for it to make sense (since it knows that ia64 and
ppc64 use descriptors for function pointers and fetches the actual
address from there).So don't make the argument be a 'unsigned long' and force everybody to
add a cast.Signed-off-by: Linus Torvalds

Fuse will use temporary buffers to write back dirty data from memory mappings
(normal writes are done synchronously). This is needed, because there cannot
be any guarantee about the time in which a write will complete.By using temporary buffers, from the MM's point if view the page is written
back immediately. If the writeout was due to memory pressure, this
effectively migrates data from a full zone to a less full zone.This patch adds a new counter (NR_WRITEBACK_TEMP) for the number of pages used
as temporary buffers.[Lee.Schermerhorn@hp.com: add vmstat_text for NR_WRITEBACK_TEMP]

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. Wysocki

The various wakeup flags and their accessor macros in struct
dev_pm_info should be available whenever CONFIG_PM is enabled, not
just when CONFIG_PM_SLEEP is on. 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. But that didn't make the regression
list for that kernel, ergo the delay in fixing it.[rjw: rebased]

Include dpm_sysfs_add() into device_pm_add(), in analogy with

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.

two different classes. When this happens, bad things happen as the

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.

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.
