The patch below does not apply to the 5.4-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to stable@vger.kernel.org.
To reproduce the conflict and resubmit, you may use the following commands:
git fetch https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/ linux-5.4.y git checkout FETCH_HEAD git cherry-pick -x 7360ee47599af91a1d5f4e74d635d9408a54e489 # <resolve conflicts, build, test, etc.> git commit -s git send-email --to 'stable@vger.kernel.org' --in-reply-to '2025062906-tightwad-overvalue-2006@gregkh' --subject-prefix 'PATCH 5.4.y' HEAD^..
Possible dependencies:
The main reason for the failure is, that the error-path implementation has changed after 5.4. But even if the patch is adopted accordingly, it will still require memdup_array_user(), which is currently missing in 5.4.y and 5.10.y (see my comment to the patch for 5.10.y).
