There are a number of reasons for this limit; not letting the kernel spend too much time on just one path is one of them. With symbolic links you can effectively generate much longer paths so some sort of limit is needed for the same reason. Linux imposes a limit of -at most 40 symlinks in any one path lookup. It previously imposed a -further limit of eight on the maximum depth of recursion, but that was +at most 40 (MAXSYMLINKS) symlinks in any one path lookup. It previously imposed +a further limit of eight on the maximum depth of recursion, but that was raised to 40 when a separate stack was implemented, so there is now just the one limit.
