The first 5 patches of this series are small cleanups and fixes to the zone block device code (zbd.c) and man page documentation. The last patch of this series implements zoneskip option support for zonemode=zbd in response to field customers request wanting to test/qualify very large capacity SMR disks without having to do full-pack read/write of the entire disk capacity, while retaining the convenience of the auomatic handling of zone write pointer alignment and zone reset of this mode (as opposed to the zonemode=strided mode). The zoneskip option support for zonemode=zbd applies only to sequential read/write workloads, allowing to skip zoneskip bytes once the current zone of a job has been fully written or read. The zoneskip value must be zone aligned.
