[PATCH] lib/dynamic_queue_limits.c: relax BUG_ON to WARN_ON in dql_complete()

From: Ard Biesheuvel
Date: Wed Oct 18 2017 - 11:45:34 EST


Even though calling dql_completed() with a count that exceeds the
queued count is a serious error, it still does not justify bringing
down the entire kernel with a BUG_ON(). So relax it to a WARN_ON()
instead.
