From 778889d8412e36e666b1e4ce108373613c84b428 Mon Sep 17 00:00:00 2001 From: Shaun Tancheff Date: Mon, 21 Nov 2016 15:52:23 -0600 Subject: [PATCH] block: apply blk_partition_remap to REQ_OP_ZONE_RESET If a ZBC device is partitioned and operations are performed on the partition the zone information is rebased to the partition, however the zone reset is not mapped from the partition to device as are other operations. This causes the API (report zones / reset zone) to be unbalanced in this regard. Checking for the zone reset op code explicitly will balance the API.
