Do directories have the same problem? I'm guessing no because every
other file type calls vfs_getattr on the lower dentry, which should link
us to xfs_vn_getattr.

There are two callers of acpi_get_device_data(), acpi_bus_get_device()
and acpi_bus_get_acpi_device(), but only one of them takes the int
return value into account. Moreover, the latter knows that it passes
a valid return pointer to acpi_get_device_data() and it properly

The upfront allocation of new_bus_id is done to avoid allocating
memory under acpi_device_lock, but it doesn't really help,
because (1) it leads to many unnecessary memory allocations for
_ADR devices, (2) kstrdup_const() is run under that lock anyway and

I'm not a fan of this change, because the new argument will only be
needed in one place where intel_pstate_get_hwp_max() and it requires

Change my email contact ahead of a likely painful eleven-month migration

break my workflow. Some day I may get used to having to email being

the same in both experiments. Clearly, reducing the jumps
between the different layers in the IOMMU code offers a
signficant performance boost in iommu_map_sg() latency.

I agree that the dax device should not be implied from the block device,

On x86 scale invariace tends to be disabled during resume from
suspend-to-RAM, because the MPERF or APERF MSR values are not as
expected then due to updates taking place after the platform
firmware has been invoked to complete the suspend transition.
