As much as I'd like to have this in, it breaks cifs so please hold this
patch until at least these two patches also get backported (I didn't
actually test the fix so not sure which is needed, *probably*
either/both):
950b03d0f66 ("netfs: Fix missing iterator reset on retry of short read")
https://lore.kernel.org/r/20240823200819.532106-8-dhowells@redhat.com ("netfs, cifs: Fix handling of short DIO read")

For some reason the former got in master but the later wasn't despite
having been sent together, I might have missed some mails and only the
first might actually be required.. David, Steve please let us know if
just the first is enough.

Either way the 9p patch can wait a couple more weeks; stuck debian CI
(9p) is bad but cifs corruptions are worse.

Thanks,
