Thanks.
Regarding the above PMR, you are absolutely correct, CIO doesn't have
to be enabled at the filesystem level (mount -o cio). When we set a
'no file system caching' policy we make a specific OS call which
utilises CIO irrespective of the mount.
In fact we prefer you do it this way because by setting CIO as a mount
option all files are CIO enabled, which may not be benefitial to some
OS files.
