One additional reason...
With current code, sleep_states(0) will not be set if compiled without CONFIG_SUSPEND, which means that S0 will also disappear from /proc/acpi/sleep. With pre-2.6.23 code it would be listed there.
I think that is even a more relevant change than the display issue and could possibly even be considered a user-space interface regression. My proposed patch fixes that too.
Note that the patch currently does not call acpi_get_sleep_type_data for S0, but (partially from Rafael's comment) I was assuming that for S0 that does not really matter. If it does, then the patch could easily be adjusted to include that. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
