If you checked the code, you would see that it's used in drivers/staging/lustre/lustre/libcfs/module.c too.
drivers/staging/lustre/lustre/libcfs/module.c:extern struct cfs_wi_sched *cfs_sched_rehash;
drivers/staging/lustre/lustre/libcfs/module.c: rc, &cfs_sched_rehash);
drivers/staging/lustre/lustre/libcfs/module.c: if (cfs_sched_rehash != NULL) {
drivers/staging/lustre/lustre/libcfs/module.c: cfs_wi_sched_destroy(cfs_sched_rehash);
drivers/staging/lustre/lustre/libcfs/module.c: cfs_sched_rehash = NULL;
