From ba80c3a572f4db2153a1a94c02f27a4566ca0995 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 11 May 2018 12:51:08 -0600 Subject: [PATCH] sata_nv: set host can_queue count appropriately libata limits the max limit for drivers to 31 anyway. We'll soon allow drivers to actually go to QD=32, but that might require some driver modifications. Before we do that, ensure that sata_nv limits the depth to 31.
