This changes the content of the control structure to use the new arrangement for attributes, shorter names and the added fields we proposed. This also changes the minor version number so user space cannot be confused (it will spit an error instead). Signed-off-by:

Move the structures needed from user space to their own header. User space can now only include zio.h (for version and name lenghts and zio-user.h). Several files are changed to reflect the new order. Signed-off-by:

I always had a hard time understanding ZIO_NAME_OBJ. Since it's only used internally, let it have "LEN" in it's own name. Signed-off-by:

The cset needs a spinlock for I/O operations. Locking the whole device seems overdue. The cset and channel need some private data, because they are allocated as arrays (while ti and bi don't need it, as container_of can be used). This adds a device-private pointer to both cset and channel, and a trigger-private pointer to the channel (this is used e.g. by the ldisc demultiplexer, to be committed later). Signed-off-by:

zio_cset interface modified. You can define a channel template to apply to all new allocated channels. This replaces the sysfs attribute channel template which is not enough. Channel template includes also the sysfs attributes to apply on each channel Signed-off-by:

The user trigger is driven by read and write. It can support one-shot devices (those that produce or consume data only when user-space read or writes) and streaming device, with their own internal timings. It is, in some way, a transparent trigger, connecting buffer and device directly. Signed-off-by:
