[PATCH v2 2/8] dma-debug: Expose nr_total_entries in debugfs

2018-12-05 Thread Robin Murphy
Expose nr_total_entries in debugfs, so that {num,min}_free_entries become even more meaningful to users interested in current/maximum utilisation. This becomes even more relevant once nr_total_entries may change at runtime beyond just the existing AMD GART debug code. Suggested-by: John Garry Sig
