Introduce a central mechanism for performing delayed ccw device work to ensure that different types of work do not overwrite each other. Prioritization ensures that the most important work is always performed while less important tasks are either obsoleted or repeated later. Signed-off-by:

This patch adds a driver for subchannels of type chsc. A device /dev/chsc is created which may be used to issue ioctls to: - obtain information about the machine's I/O configuration - dynamically change the machine's I/O configuration via asynchronous chsc commands Signed-off-by:

Introduce a private pointer in struct subchannel to store per-subchannel type data (cannot use dev->priv since this is already used for something else). Create a new header io_sch.h for I/O subchannel specific structures and instructions. Signed-off-by:
