##### check_hw_slab_unreclaimable
`check_hw_slab_unreclaimable max_kb`

`check_hw_slab_unreclaimable` compares the amount of slab unreclaimable memory to the maximum provided (in kB). If the slab unreclaimable is greater than _max_kb_ kilobytes, the check fails.

_**Example** (require less than 5 GB unreclaimable)_: `check_hw_slab_unreclaimable 5242880`
