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.
