Hi Joe,

Could you drop those patches. I just used them to test the ps->init 
function and sleeping/locking stuff, and as a RFC/example to make sure 
using the blk_execute_rq or elv_add_request fns was not violating any 
block layer guidelines.

The TUR command being sent just tests a path. The command I need to send 
is a little more complicated (I mean ugly).

I just do not want to confuse someone with a fastt xxx, in thinking DM 
has RDAC or AVT support.

Thanks,

Mike
