Sage Weil 45f2e081f5 ceph: avoid divide by zero in __validate_layout() ... If "l->stripe_unit" is zero the the mod on the next line will cause a divide by zero bug. This comes from the copy_from_user() in ceph_ioctl_set_layout_policy(). Passing 0 is valid, though (it means "do not change") so avoid the % check in that case.
