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.
