Dear release team
Please do tell me if I can upload lxcfs 3.0.3-2+deb10u1 to stable.
A canonical employee reported a swap accounting bug that could make a
container look like it uses all the host's swap. The fix being minor,
I've designed a patch I'd like to have uploaded to stable.
The upload is not done yet, as I'd rather wait for your opinion.
The bug is already fixed in testing, as this patch has also been included in
lxcfs 4.
Thanks in advance!
