This reduces +the number of forks and the pressure on the CPU significantly, because +cloned event processes no longer cause page faults in the main daemon. +After the events have settled, a few worker processes stay around for +future events, all others get cleaned up. + +To be able to use signalfd(), udev depends on kernel version 2.6.25 now. +Also inotify support is mandatory now to run udev. + The format of the queue exported by the udev damon has changed. There is -no longer a /dev/.udev/queue/ directory. The queue can be accessed with -udevadm settle and libudedv. +no longer a /dev/.udev/queue/ directory. The current event queue can be +accessed with udevadm settle and libudedv. + +Libudev does not have the unstable API header anymore. From now on, +incompatible changes will be handled by bumping the library major version. + +To build udev from the git tree gtk-doc is needed now. The tarballs will +build without it and contain the pre-built documentation. An online copy +is available here: + http://www.kernel.org/pub/linux/utils/kernel/hotplug/libudev/ udev 142 ========
