Change subject: Don't update acl_time in mdcache_entry_t when ACL is preserved.
......................................................................
Don't update acl_time in mdcache_entry_t when ACL is preserved.
This change restores the previous acl_time when ACL is not refreshed
from the FSAL but only preserved.
Issue:
- If ACL is already cached for an object and later if ACL is directly
updated in backend (not via the NFS protocol), nfs4_getfacl returns stale
ACL from MDCache.
- nfs4_getfacl first sends a GETATTR without ATTR_ACL, which updates
acl_time even though ACLs are not refreshed.
- The later GETATTR with ATTR_ACL incorrectly uses the stale cached ACL
because the updated acl_time suggests the ACL is still valid.
