[LTP] [PATCH] lib: switch cgroup bit-fields from signed to unsigned int

[Petr Vorel]

Hi Li,

> There is a problem in cgroup lib that the declearation int
> can lead to -1 during the | operation.

> Becasue if the field contains uninitialized garbage data,
> a bit-field declared as int could interpret 0b1 as -1 due
> to signed arithmetic.

> By changing the type to unsigned int, the issue is avoided
> since unsigned fields cannot represent negative values.
