Good day, i'm trying to run this test script
"**cpuset_base_ops_testset.sh**" but when i do that i have multiple
errors related to some missing devices under **/dev/cpuset/** here is
the output:
```
opt/ltp/testcases/bin/cpuset_base_ops_testset.sh: line 58:
/dev/cpuset/cpus: Permission denied
cat: /dev/cpuset/cpus: No such file or directory

opt/ltp/testcases/bin/cpuset_base_ops_testset.sh: line 58:
/dev/cpuset/mems: Permission denied
cat: /dev/cpuset/mems: No such file or directory

opt/ltp/testcases/bin/cpuset_base_ops_testset.sh: line 58:
/dev/cpuset/memory_pressure: Permission denied
cat: /dev/cpuset/memory_pressure: No such file or directory
```
I only posted a few errors but are many of them with the same message
"Permission denied"
Note: I already tried to run it with runltp tool but I have the same errors

I tried changing the script execution permission and also running it
as root but doesn't change anything do you know what could be wrong?
