Only a few sysfs attributes have poll/select support, and I don't know if
that's enough for inotify or if you also need some sort of special inotify
support in sysfs (something I don't know if is even possible but I could
check). The attributes with poll/select support are documented in the
thinkpad-acpi driver documentation on the kernel sources, at
Documentation/laptops/thinkpad-acpi.txt. If inotify is indeed impossible,
you will need perl, python or C to deal with poll/select, shell can't do it
AFAIK.
