Pankaj Raghav ea5e101fb6 block: use largest_zero_folio in __blkdev_issue_zero_pages() ... Use largest_zero_folio() in __blkdev_issue_zero_pages(). On systems with CONFIG_PERSISTENT_HUGE_ZERO_FOLIO enabled, we will end up sending larger bvecs instead of multiple small ones. Noticed a 4% increase in performance on a commercial NVMe SSD which does not support OP_WRITE_ZEROES. The device's MDTS was 128K. The performance gains might be bigger if the device supports bigger MDTS.
