from the address space. This generally corresponds to either a
truncation, punch hole or a complete invalidation of the address
space (in the latter case 'offset' will always be 0 and 'length'
- will be PAGE_CACHE_SIZE). Any private data associated with the page
+ will be PAGE_SIZE). Any private data associated with the page
should be updated to reflect this truncation. If offset is 0 and
- length is PAGE_CACHE_SIZE, then the private data should be released,
+ length is PAGE_SIZE, then the private data should be released,
because the page must be able to be completely discarded. This may
be done by calling the ->releasepage function, but in this case the
release MUST succeed.

but also it allows of more flexibility in the handling of devices during the

+Drivers in ->remove() callback should undo the runtime PM changes done
+in ->probe(). Usually this means calling pm_runtime_disable(),
+pm_runtime_dont_use_autosuspend() etc.

The user space can effectively disallow the driver of the device to power manage
it at run time by changing the value of its /sys/devices/.../power/control
attribute to "on", which causes pm_runtime_forbid() to be called. In principle,
