--- Comment #1 from Conrad Meyer <cem at freebsd.org> ---
CURRENT is a WITNESS kernel.  11.1 is not.  I suspect 11.2-BETA2 is not either. 
 Non-WITNESS kernels will never print LORs.  So the distinction from 11.x is
not really surprising.

Here's the transcribed LOR for other readers:
lock order reversal:
 1st ... isofs (isofs) @ .../sys/kern/vfs_mount.c:1335
 2nd ... devfs (devfs) @ .../sys/kern/vfs_subr.c:2570

(No other stack or previous order info.)

I'm not sure if this is a known LOR or not.  I'll look briefly.
