There are four level slabs:
CPU
CPU_PARTIAL
PARTIAL
FULL
In current implementation, cpu_slabs sysfs would give statistics including
the first two levels. While there is another sysfs entry cpu_partial_slabs
gives details on the second level slab statistics. Since each cpu has one
slab for the first level, the current cpu_slabs output is easy to be
calculated from cpu_partial_slabs.
This patch removes the cpu_partial data in cpu_slabs for more specific slab
statistics and leave room to retrieve objects and total objects on CPU
level in the future.
