The orphan_file feature has landed in for the 5.15 merge window.  When
enabled, it provides multiple blocks to store the set of orphaned
inodes, which provides parallelism for parallel truncate and unlink
operations.

It requires a development version of e2fsprogs to use, and so the
zero-day bot won't be able to test it for a little while.
