meta information, which directly governs the

This value is specified in bytes of KVA space

Care should be taken

amount of configured swap exceeds 1/2 the

kernel-supported swap. The default 70MB allows

kernel-supported swap.

The default 70MB allows

the kernel to support a maximum of (approximately)

14GB of configured swap. Only mess around with

maximum is 200MB. This parameter is used to

The default maximum is 200MB.

This parameter is used to
