>
> Current ACL limits are only on the total number of entries.
> But there can be a situation where number of default entries for a directory
> will be more than half of the maximum entries, i.e. > 16.
> In such case, under this parent directory only files can be created which
> will have ACLs inherited using parent's default entries.
> But when directories are created, total number of entries will be more than
> the maximum allowed, because sub-directories copies both inherited ACLs as
> well as default entries.
> Since currently there is no check while copying ACLs from default ACLs
> directory creation succeeds, but any modification (only permission on one
> entry also) on the same ACL will fail.
> So it would be better to restrict the default entries to 16.
