[PATCH v6 13/18] rnull: move driver to separate directory
From: Andreas Hindborg <a.hindborg@kernel.org>
Date: 2025-08-22 12:15:39
Also in:
lkml, rust-for-linux
Subsystem:
block layer, block layer device driver api [rust], the rest · Maintainers:
Jens Axboe, Andreas Hindborg, Linus Torvalds
The rust null block driver is about to gain some additional modules. Rather
than pollute the current directory, move the driver to a subdirectory.
