Are the dependencies correct?

Based on your suggestion, I checked and it turned out that PROC_FS is not
the correct dependency, but DEBUG_FS. 

I guess you missed something.

Shoud I change it to DEBUG_FS?

Please, double check.

Thing is that proc_sched_show_task() still wants PROC_FS, i've not yet
found a suitable debugfs based location for that.

And DEBUG_FS doesn't need a dependency; it has complete DEBUG_FS=n
wrappers and will build fine. Arguably selecting SCHED_DEBUG without
DEBUG_FS is daft, but it should work.
