commit 21f54ddae449f4bdd9f1498124901d67202243d9
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Mon Oct 3 21:03:48 2016 -0700

    Using BUG_ON() as an assert() is _never_ acceptable
    
    That just generally kills the machine, and makes debugging only much
    harder, since the traces may long be gone.
    
    Debugging by assert() is a disease.  Don't do it.  If you can continue,
    you're much better off doing so with a live machine where you have a
    much higher chance that the report actually makes it to the system logs,
    rather than result in a machine that is just completely dead.
    
    The only valid situation for BUG_ON() is when continuing is not an
    option, because there is massive corruption.  But if you are just
    verifying that something is true, you warn about your broken assumptions
    (preferably just once), and limp on.
