From c206a389c97c9533971cd05eed69b49f535cc193 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Tue, 21 Dec 2021 08:20:31 +0100 Subject: ata: libata: tracepoints for bus-master DMA Add tracepoints for bus-master DMA and taskfile related functions. That allows us to drop the relevant DPRINTK() calls.
