Unfortunately, I don't see a fix, short of backporting support for the
.bin_size function, as this is exactly the problem that function solves.
It should work out in practice. (I introduced the .bin_size function)
The race I describe is unlikely, particularly if attribute groups are created
once and then not disturbed. But note that the Hyper-V fcopy group can
get updated in a running VM via update_sysfs_group(), which also calls
create_files(). Such an update might marginally increase the potential for
the race and for getting the wrong size. Still, I agree it should work out
in practice.

hi Thomas,
Would it be possible to port your changes on 6.12 kernel, to avoid such
race conditions?
Possible, surely. But Greg has to accept it.
And you will need to do the backports.
Or if it has a lot of dependencies, or if you have a
follow-up advice, please let us us know.
Not more than mentioned before.
Thomas
Acked. Thanks.
Regards,
Naman
