Hi all,

After merging the block tree, today's linux-next build (x86_64
allmodconfig) failed like this:

error: unused import: `c_str`
--> /tmp/next/build/drivers/block/rnull/configfs.rs:6:5
|
6 | c_str,
| ^^^^^
|
= note: `-D unused-imports` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(unused_imports)]`

error: aborting due to 1 previous error

Caused by commit

4cef2fcda3ada (rnull: replace `kernel::c_str!` with C-Strings)

I have used the version from 20260116 instead.
