So as correctly described earlier in the thread by Jerome, forcing
cached_dynamic_acls=1 in-kernel when generate_node_acls=1 is set ended
up being the (best) default for demo-mode so that things 'just work' for
typical user configurations, given that cached_dynamic_acls=1 is
required in order to keep active PR metadata around during typical
session (I_T nexus) resets.
The reason that cached_dynamic_acls is still exposed as a TPG attribute
is primarily for large public demo-mode setups (like boot.kernel.org was
originally supposed to be :) where it's useful to release the
dynamically allocated se_node_acl each time I_T nexus shutdown/timeout
occurs, in order to avoid left-over se_node_acl memory with lots of
transient initiators coming and going.
Thanks Nic.
Just to clarify for everyone, one of the things implied here is that
even though cache_dynamic_acls is forced to 1 when generate_node_acls is
set (demo mode), you can flip it back to 0 if needed, while still in
demo mode. Is that correct?
