Hi all,

I just had the occasion to test the new patch as landed in arch linux 
5.14.7. Unfortunately it does not work for me. Attached you can find a 
modification that works for me, though I am not really sure why 
write_behind seems not to be set to true on my configuration. If there 
is any more data I can provide to help you to investigate, please let 
me know.

Thanks for the report!  As commented in bugzilla, this is because 
write-behind
IO still happens even without write-mostly device. I will send new patch 
after
you confirm it works.
