I'm glad that solved your problem, thanks for taking the time to test it out.

I think backporting it to the stable kernels would be okay, but I'd
prefer to let it get some more testing in linux-next first if that's
okay with you.  Since we are currently at v6.3-rc5 and this patch is
scheduled to go up to Linus during the next merge window, it might
make the most sense to give this two more weeks in -next, let it land
in Linus' tree, and they ask the stable team for a backport ("Option
2" in the stable kernel docs):

Thoughts?

In addition to the ocfs2 patch mentioned above, there is a similar
reiserfs patch which should probably also be backported:
