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).

68b68db9c0 Zero metadata if on-disk version differs from current 
Kernel adapter now returns is_cache_device=1 and newly added
metadata_compatible=0 in case of metadata detected with
differing version (instead of is_cache_device = 0).

This allows zero-superblock command to recognize old
cache instance and clear it.

casadm --script --check-cache-device still returns 'Is cache'='no'
in this case, as this layer only cares about metadata in current
version to be able to detect dirty datas tatus.

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