This is another way to see the same information about swap space reported by swapinfo. In the column labeled
Priority, the smaller numerical value indicates higher priority, except for pseudo-swap, which is used only when
all device swap is exhausted.

The operating system must allocate a certain amount of kernel memory for each of the objects actually in use. From
the example, there are 111 shared memory segments in use by applications, each of which requires a modest
amount of kernel memory for its management.
