[ruby-core:83406] [Ruby trunk Feature#13867] Copy offloading in IO.copy_stream
From:

ruby-core #83406
Issue #13867 has been updated by shyouhei (Shyouhei Urabe).
We took a look at this issue at yesterday's developer meeting and agreed with Eric here; it can be automatically applied whenever possible. Seems there are no practical reasons to disable this feature.
----------------------------------------
Feature #13867: Copy offloading in IO.copy_stream
https://bugs.ruby-lang.org/issues/13867#change-67371
* Author: Glass_saga (Masaki Matsushita)
* Status: Open
* Priority: Normal
* Assignee:
* Target version: 2.5
----------------------------------------
In linux 4.5, the copy offloading feature with copy_file_range(2) was introduced.
This patch enables IO.copy_stream to use it.
If "offload" keyword argument is specified, IO.copy_stream will try copy offloading.
```ruby
IO.copy_stream("src", "dst", offload: true)
```
If copy offloading is not available on the system, "offload" option will be ignored.
When "src" and "dst" are not in the same filesystem, copy_file_range(2) must fail with EXDEV.
In this case, IO.copy_steram will fallback to another method (sendfile(2) or read/write) silently.
It depends on the filesystem what offloading techniques will be used.
Copy offloading is optional in IO.copy_stream because some techniques may change the current behavior.
