[PATCH 6/8] scsi: sd_zbc: Limit zone write locking to sequential zones

2017-09-01 Thread Damien Le Moal
Zoned block devices have no write constraints for conventional zones so write locking of conventional zones is not necessary and can hurt performance. To avoid this, introduce the seq_zones bitmap to indicate if a zone is a sequential one. Use this information to allow any write to be issued to con
