Subject: [ROSE] Bug : waiting for rose module to become free

A nastly bug is still pending in ROSE module that prevents it to be removed.
When trying to remove rose module we enter into an endless loop with displayed message :
 "waiting for rose module to become free"
A patch from Richard Stern had been committed a while ago but it did not get a chance to be applied.

Since then, there have been some changes in af_rose.c and net code architecture that prevents simply adding missing dev_put(dev) in present kernel.

>From time to time we can observe a negative count (-1 for integer value is displayed as 65535 in /proc/net/rose_neigh) that probably means there is a bug in rose module refcount (??).
