Detailed Description

Disk scratch write batching, independent of resident cache policy.

Set struct_size = sizeof(pf_scratch_io_policy_v1), version = 1 and both reserved words to zero. write_batch_bytes is successful write traffic in bytes: default 65536; every uint64_t value is valid. Positive values retain the before-next-batch sync/discard order. Zero syncs/discards each positive transfer before write/write_some returns success, including short writes. This is not a logical history limit or a physical-memory guarantee. The fixed clean-read and userspace sequence windows remain unchanged.
