Unlike space_cache, which is enabled by default these days, inode_cache must be specifically enabled every time it is to be used. So simply not including the inode_cache mount option when doing the original mount means it's disabled. Meanwhile, the noinode_cache flag is simply one of the mount-option negators, to allow turning off a mount option on an existing mount when it is remounted, to avoid having to fully umount and do a fresh mount, to deactivate the option. So simply don't include inode_cache when doing the original mount to disable it, or if for whatever reason it's enabled and you want to disable it on a remount, use -o remount,noinode_cache for the remount, and it'll disable inode_cache if the filesystem was already mounted with it enabled. -- Duncan - List replies preferred.
