Andrew - I enclose a fix-patch for the issue kindly reported in [0] by Yi
Lai. Since you've not sent the PR to Linus yet maybe you could squash this
in? Otherwise obviously one for 6.15-rc1.

I've tested against the repro and confirm it fixes it, also the fix is
'obvious' as is the cause. I have replied to [0] with an explanation there
also inline.

Apologies for missing this before!

Thanks, Lorenzo
