If changelog will be removed, then how people will detect what happend after previous release? Kevent is a generic subsytem which allows to handle event notifications. It supports both level and edge triggered events. It is similar to poll/epoll in some cases, but it is more scalable, it is faster and allows to work with essentially eny kind of events. Events are provided into kernel through control syscall and can be read back through mmaped ring or syscall. Kevent update (i.e. readiness switching) happens directly from internals of the appropriate state machine of the underlying subsytem (like network, filesystem, timer or any other). I will put that text into introduction message. > Pavel > -- > Thanks, Sharp! -- Evgeniy Polyakov
