Hello Christoph,

My goal is to realize this proposal without adding hooks for out-of-tree
code in the upstream kernel. What I had in mind is to raise the
abstraction level of the API between LIO core and target drivers a
little bit (e.g. by using accessor functions where necessary instead of
accessing structure members directly) and to implement the translation
between this API and the SCST API in a translation header file.
#including that last header file should be sufficient to build a target
driver against the SCST core. Other changes might also be necessary,
e.g. general code cleanup, simplification or making the API between core
and target drivers more consistent.

Bart.
