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
