Hi Konard,

I just pushed most of your recommend cleanups for target_core_base.h to
lio-core-2.6.git/lio-4.0.  The cleanup series has been posted on
lio-devel list to prevent extra noise on linux-scsi, et al, but for
reference the shortlog and diffstat are attached below..  I did not dive
into intermixed struct + #defines, but I am still pretty indifferent on
this particular item.

Please have a look and feel free to make additional comments.

Thanks again!
