That's right of course. Even this shouldn't be a problem as it is called by a single instance, per autofs mount, of the daemon only. A fair amount of effort has gone into trying to make the autofs4 module independent of the BKL over time. However I would still rather not do the change concurrently with the ioctl changes.
