The impression I got from previous discussions was that upstream did not want things that were built conditionally around APIs that did not exist in mainline nor stub implementations for things that were not agreed upon. We could easily either #if defined(CONFIG_SUSPEND_BLOCKERS) or submit a suspend_blockers.h that just makes everything a no-op, if that's an acceptable transition vehicle. I didn't think either were an option open to us. > In any case, this is not to suggest that the suspend-blocker bits are > 'impossible' to merge.

I think we hit the point where Rafael and Matthew signed off on things and thought "aha, linux-pm maintainers are happy, now we're getting somewhere" only to realize the light at the end of the tunnel was a bit further out than we anticipated ^^ Brian -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
