Most of z3fold operations are in-page, such as modifying z3fold

Markus reported that there's a weird behavior on perf top --hierarch
regarding the column length. Looking at the code, I found a debious
code which affects the symtoms. When --hierarchy option is used, the
last column length might be inaccurate since it skips to update the
length on leaf entries.

Since commit ca065d0cf80f ("udp: no longer use SLAB_DESTROY_BY_RCU")
the udp6_lib_lookup and udp4_lib_lookup functions are only
provided when it is actually possible to call them.
However, moving the callers now caused a link error:

Hello,
This is another update of the patchset for adding proper runtime PM
support to Exynos IOMMU driver. This has been achieved by using recently
introduced device links, which lets SYSMMU controller's runtime PM to
follow master's device runtime PM state (the device which actually
performs DMA
Some drivers would like to record stacktraces in order to aide leak
tracing. As stackdepot already provides a facility for only storing the
unique traces, thereby reducing the memory required, export that
functionality for use by drivers.
The code was originally created for KASAN and moved under l
This patch adds runtime pm implementation, which is based on previous
suspend/resume code. SYSMMU controller is now being enabled/disabled mainly
from the runtime pm callbacks. System sleep callbacks relies on generic
pm_runtime_force_suspend/pm_runtime_force_resume helpers. To ensure
internal stat
__sysmmu_enable/disable functions were designed to do ref-count based
operations, but current code always calls them only once, so the code for
checking the conditions and invalid conditions can be simply removed
without any influence to the driver operation.

Remove remaining leftovers of the ref-count related code in the
__sysmmu_enable/disable functions inline __sysmmu_enable/disable_nocount
to them. Suspend/resume callbacks now checks if master device is set for
given SYSMMU controller instead of relying on the activation count.

To avoid possible races, set master device pointer in each SYSMMU
controller once on boot. Suspend/resume callbacks now properly relies on
the configured iommu domain to enable or disable SYSMMU controller.
While changing the code, also update the sleep debug messages and make
them conditional.

This patch reworks locking in the exynos_iommu_attach/detach_device
functions to ensure that all entries of the sysmmu_drvdata and
exynos_iommu_owner structure are updated under the respective spinlocks,
while runtime pm functions are called without any spinlocks held.

Remove excessive, useless debug about skipping TLB invalidation, which
is a normal situation when more aggressive power management is enabled.

As fast_switch() may get called with interrupt disable mode, we cannot
hold a mutex to update the global_pstate_info. So currently, fast_switch()
does not update the global_pstate_info and it will end up with stale data
whenever pstate is updated through fast_switch().
As the gpstate_timer can fir
