Chapter 14: Allocating memory
The kernel provides the following general purpose memory allocators:
-kmalloc(), kzalloc(), kcalloc(), and vmalloc(). Please refer to the API
-documentation for further information about them.
+kmalloc(), kzalloc(), kcalloc(), vmalloc(), and vzalloc(). Please refer to

The preferred form for passing a size of a struct is the following:
- Specify a bandwidth rate on particular device for root group. The format
for policy is "<major>:<minor> <byes_per_second>".
- echo "8:16 1048576" > /sys/fs/cgroup/blkio/blkio.read_bps_device
+ echo "8:16 1048576" > /sys/fs/cgroup/blkio/blkio.throttle.read_bps_device
Above will put a limit of 1MB/second on reads happening for root group
on device having major/minor number 8:16.
1024+0 records out

the format.
- echo "<major>:<minor> <rate_io_per_second>" > /cgrp/blkio.read_iops_device

+desirable to suspend the device as soon as ->probe() has finished, so the driver
+core uses pm_runtime_put_sync() to invoke the subsystem-level idle callback for
+the device at that time.
+
+Moreover, the driver core prevents runtime PM callbacks from racing with the bus
+notifier callback in __device_release_driver(), which is necessary, because the
+notifier is used by some subsystems to carry out operations affecting the
+runtime PM functionality. It does so by calling pm_runtime_get_sync() before
+driver_sysfs_remove() and the BUS_NOTIFY_UNBIND_DRIVER notifications. This
+resumes the device if it's in the suspended state and prevents it from
+being suspended again while those routines are being executed.
+
+To allow bus types and drivers to put devices into the suspended state by
+calling pm_runtime_suspend() from their ->remove() routines, the driver core
+executes pm_runtime_put_sync() after running the BUS_NOTIFY_UNBIND_DRIVER
+notifications in __device_release_driver(). This requires bus types and
+drivers to make their ->remove() callbacks avoid races with runtime PM directly,
+but also it allows of more flexibility in the handling of devices during the
+removal of their drivers.
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

-/* Okay, this is some magic that I worked out and the reasoning behind it...
-
- The biggest problem with any USB device is of course: "what to do
- when the user unplugs the device while it is in use by an application?"
- We have several options:
- 1) Curse them with the 7 plagues when they do (requires divine intervention)
- 2) Tell them not to (won't work: they'll do it anyway)
- 3) Oops the kernel (this will have a negative effect on a user's uptime)
- 4) Do something sensible.
-
- Of course, we go for option 4.
-
- It happens that this device will be linked to two times, once from
- usb_device and once from the video_device in their respective 'private'
- pointers. This is done when the device is probed() and all initialization
- succeeded. The pwc_device struct links back to both structures.
-
- When a device is unplugged while in use it will be removed from the
- list of known USB devices; I also de-register it as a V4L device, but
- unfortunately I can't free the memory since the struct is still in use
- by the file descriptor. This free-ing is then deferend until the first
- opportunity. Crude, but it works.
-
- A small 'advantage' is that if a user unplugs the cam and plugs it back
- in, it should get assigned the same video device minor, but unfortunately
- it's non-trivial to re-link the cam back to the video device... (that
- would surely be magic! :))
