Each value line shows the memory information for a slab. The Number field shows the number
of objects (memory blocks) allocated to the module. The Active field shows the number of
objects used. If the percentage of the used objects keeps increasing, the slab might have
memory leakage issues.
2.
Display the memory call information for the slabs that might have leak problems. This example
uses the kmalloc-2048 slab.
