[sbp2] external hard disk shutdown timer

[olecom@mail.ru]

Hallo ! Let me ask a question.

I couldn't change some values (f.e IDLE or ICT), while its
"changing" flag is "y".

Would you like to explain meaning of that flag and, possibly,
why change doesn't apply ? Maybe i'm doing or understanding
something wrong ?

All i want is to switch off timers (AFAIR from spcecs i've found t10.org),
that shutdown ieee1394/usb-storage external HDD.

TIA.
