Subject: [PATCH] Force IPv6 FIB gc on device shutdown
Date: Fri, 9 Apr 2004 17:39:01 +0200 [thread overview]
Message-ID: <20040409173901.62ebf75b.ak@suse.de> (raw)
A few people reported problems with shutdown complaining about lost reference
counts in network devices. The problem was that the IPv6 FIB kept some
device references around and only dropped it on the next GC timer run, which
happens only every 10s.
This patch forces a garbage collection on device shutdown.
