Subject: About the patch " block: flush writeback dwork before detaching a
 bdev inode from it"

Hi Jan,

This is about the patch "block: flush writeback dwork before detaching a
bdev inode from it" you sent a month ago to fix a panic hit by Dimitry:
https://patchwork.kernel.org/patch/9187409/

We hit the same issue on our side, and gave your patch a try, and it
fixed the issue.

Is there any chance to get this patch accepted upstream ?

Cheers,
Laurent.
