Write-only (WO) cache mode is similar to Write-back (WB), however
read operations do not promote data to cache. Reads are mostly
serviced by the core device, only dirty sectors are fetched from
the cache.
Write-only cache mode is behaving similarly to Write-back with
respect to flushing dirty data. For example it is required to
explicitly enable/disable flushing when changing cache mode
from WO to something other than WB.
