Description

I noticed this on a soak node running 2.10.58_139_g630cd49.

[root@soak-20 ~]# addr2line -e /usr/bin/lfs --functions --inlines 0x40dc1a
??
/usr/src/debug/lustre-2.10.58_139_g630cd49/lustre/utils/lfs.c:4908

This is in lfs_setdirstripe():

                                /* get \a r between [0, nr) */
                                r = rand() % nr;
