Petersen" Subject: [PATCH] block: all zones zone management operations Date: Thu, 26 Mar 2020 13:30:12 +0900 Message-Id: <20200326043012.600187-1-damien.lemoal@wdc.com> X-Mailer: git-send-email 2.25.1 MIME-Version: 1.0 Sender: linux-block-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-block@vger.kernel.org Similarly to the zone write pointer reset operation (REQ_OP_ZONE_RESET), the zone open, close and finish operations can operate on all zones of a ZBC or ZAC SMR disk by setting the all bit of the command. Compared to a loop issuing a request for every zone of the device, the device based processing of an all zone operation is several orders of magnitude faster. While resetting all zones of a device was already supported with REQ_OP_ZONE_RESET_ALL, a similar implementation for the open, close and finish operations would introduce 3 more request types and complicate the code. To avoid this, the REQ_ALL_ZONES request flag is introduced to indicate that a zone management operation request (REQ_OP_ZONE_RESET, REQ_OP_ZONE_OPEN, REQ_OP_ZONE_CLOSE or REQ_OP_ZONE_FINISH) must operate on all zones of the target device. This allows removing entirely the special processing for REQ_OP_ZONE_RESET_ALL. Since an all zone management operation can only be executed if the block device represents a physical device, the request queue flag QUEUE_FLAG_ZONE_RESETALLi is renamed as QUEUE_FLAG_ALL_ZONES_MGMT to allow device drivers to indicate that the device can accept all zones zone management requests. THe scsi sd_zbc code is modified accordingly to allow setting the all bit in ZBC_OUT commands. The null_blk driver is also modified to add processing for the open all, close all and finish all operations.
