[ltp] hdapsd looking for non-existent file under /sys

[Dimitris Kogias]

Lenovo X60 1709-CTO
BIOS 2.10
Debian 2.6.20 kernel
tp_smapi Debian package 0.31-1 from
http://debian.die-welt.net/pool/main/tp-smapi/ built using m-a

Both hdaps and tp_smapi modules are loaded - in fact hdaps-gl only works
when they are both loaded.

hdapsd however (Debian unstable, version 20061007-2) fails to run
because /sys/block/sda/queue/protect is not present.  Here's an strace:

Any ideas?  Should hdapsd be looking elsewhere for that file?

Thanks
