scsi: sd: sd_zbc: Verify that the zone size is a power of two
The following check in sd_zbc_cmnd_checks() can only work correctly if the zone size is a power of two: if (sector & (sd_zbc_zone_sectors(sdkp) - 1)) /* Unaligned request */ return BLK_STS_IOERR; Hence this patch that verifies that the zone size is a power of two.
