Description
I want to continue using `copy_file_range` if and only if 1st 64 KiB was reflink'ed for performantical reason. The usecase is covered by using FIEMAP for copied bytes. There is [FICLONERANGE](https://github.com/bytecodealliance/rustix/pull/1624), but it is difficult to use due to alignment.
There is already existing safe wrapper: https://github.com/lilydjwg/fiemap-rs .
