Be it per-cotroller, or per-device, I think it is great
to have the timeout variable controllable (possibly) from
userland programs (via ioctls and such.)
I believe that Alan Cox bumped the timeout to 30 seconds
after hearing complaint about too short timeout
from people using RAID (and I also chimed in saying
that old disks tend to take a long time when read
error occurs and recovery is attempted.).
I think this is in the right direction, and
many other timeout values ought to be variables, I think.
Happy Hacking,
