584ef99143 Change time parameter type in printing 
Type of `dirty_for` in structs needs to be unified.
Values stored in these fields (both in cache and core info structs)
are  unsigned 64-bits ints but `dirty_for`s were unsigned 32-bits ints
(vide changes in OCF).

Extend CAS interface with Write-only cache mode
 2019-06-14 12:41:43 +02:00

ffa1f4b067 Extend CAS interface with Write-only cache mode 
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.
