If the unthinkable happens and your kernel oopses, you may need the
ksymoops tool to decode it, but in most cases you don't.
In the 2.6 kernel it is generally preferred to build the kernel with
CONFIG_KALLSYMS so that it produces readable dumps that can be used as-is

If for some reason your kernel is not build with CONFIG_KALLSYMS and
you have no way to rebuild and reproduce the Oops with that option, then
you can still decode that Oops with ksymoops.

In ancient (2.4 and earlier) kernels, the nfs server needed to know

With 2.6 we have the option of having the kernel tell mountd when it
gets a request from an unknown host, and mountd can give appropriate
export information to the kernel. This removes the dependency on
rmtab and means that the kernel only needs to know about currently

Why: It makes no sense to switch the tuner to radio mode by calling

incremented by the driver core before executing ->probe(). Still, it may be
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

- If you are upgrading between releases using the stable series patches
(for example, patch-2.6.xx.y), note that these "dot-releases" are
not incremental and must be applied to the 2.6.xx base tree. For
example, if your base kernel is 2.6.12 and you want to apply the
2.6.12.3 patch, you do not and indeed must not first apply the
2.6.12.1 and 2.6.12.2 patches. Similarly, if you are running kernel
version 2.6.12.2 and want to jump to 2.6.12.3, you must first
reverse the 2.6.12.2 patch (that is, patch -R) _before_ applying
the 2.6.12.3 patch.
(for example, patch-3.x.y), note that these "dot-releases" are
not incremental and must be applied to the 3.x base tree. For
example, if your base kernel is 3.0 and you want to apply the
3.0.3 patch, you do not and indeed must not first apply the
3.0.1 and 3.0.2 patches. Similarly, if you are running kernel
version 3.0.2 and want to jump to 3.0.3, you must first
reverse the 3.0.2 patch (that is, patch -R) _before_ applying
