2008-01-26[S390] cio: Introduce subchannel->private.Cornelia Huck
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: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
