htop only show 1 cpu core in lxcfs 6.0.0

[rydeng]

lxcfs 6.0.0 as follows:

but in lxcfs 5.0.4 as follows:

the pod has the same cpu limits, there are some new configs in 6.0.0?

Sorry, I found maybe my build has some error, beacause when I build 5.0.4 tag code, there is also 1 core in pod. my build is as follows:

I do not know why my build lxcfs cannot correctly show the right core num in htop

[rydeng]

I know because my system has a fusermount3 with 3.10.2, but it use 2.9.9 fuse. I need to specify the fuse version to use version 2.
