I backed the change out to restore the build, but I wonder how this
should be fixed.
3ware's tw_cli is only available as a FreeBSD or Linux binary. The
FreeBSD version hardcodes the twa major at 187. There is the same
problem for twe at major 146. I see 3 options
1) Tag the major 187 as reserved in the MI range and only define it on
2) Use a MD major for twa, and patch freebsd_sys_mknod() so that 187
gets translated into the right major
3) Use a MD major for twa, and patch the tw_cli binary so that the right
major gets used.
What's the best way?
since the hardcoded value is for freebsd, #2 seems the right place.
