[PATCH GIT PULL 8/9] rnull: configfs: add power to configfs features

From: Andreas Hindborg

Date: Tue Sep 29 2026 - 05:35:52 EST


From: Malte Wechter <maltewechter@xxxxxxxxx>

features displayed by configfs for rnull was inconsistent with the
actual features available. This correctly exposes `power` as a feature,
which is also consistent with the C null_blk driver.

Fixes: d969d504bc13 ("rnull: enable configuration via `configfs`")
