[PATCH 0/9] rnull: add configfs, remote completion to rnull
From: Andreas Hindborg
Date: Mon Jun 16 2025 - 09:26:39 EST
This series adds configuration via configfs and remote completion to
the rnull driver. The series also includes a set of changes to the
rust block device driver API: a few cleanup patches, and a few features
supporting the rnull changes.
This series is a smaller subset of the patches available in the
downstream rnull tree. I hope to minimize the delta between upstream
and downstream over the next few kernel releases.
