The linux/ directory is divided in two specific directories which are dev/
and src/. If a file is present in dev/, the Makefile uses it prior to the
one in src/. There is no current_set symbol in linux/dev/kernel/sched.c.
I've only seen current->state in the driver I'm testing with. There could
be other fields as other drivers are added.

I've created a dummy current_set symbol, and code using it just has no
