Hi, Greg

This is the manual adaptation version for 6.1, for 6.6/6.12 commit
8542870237c3 ("md: fix mddev uaf while iterating all_mddevs list") can
be applied cleanly, can you queue them as well?

Thanks!

  md: factor out a helper from mddev_put()

I noticed that the change 8542870237c3 was queued for 6.6.y and 6.12.y
and is in the review now, but wonder should we do something more with
6.1.y as this requires this series/manual adaption?

Or will it make for the next round of stable updates in 6.1.y? 

(or did it just felt through the cracks and it is actually fine that I
ping the thread on this question).

Regards,
Salvatore

This fell through the cracks and yes, it is great that you pinged it.
I'll queue it up for the next release, thanks!

Thank you! Very much appreciated! (People installing Debian will be
happy as it affects kernel under certiain circumstances, cf.
https://bugs.debian.org/1086175, https://bugs.debian.org/1089158, but
was longstanding already).

Thank you,
Regards,
Salvatore
