This is a note to let you know that I've just added the patch titled
neigh: recompute reachabletime before returning from neigh_periodic_work()
to the 3.13-stable tree which can be found at:
http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary
The filename of the patch is:
neigh-recompute-reachabletime-before-returning-from-neigh_periodic_work.patch
and it can be found in the queue-3.13 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree,
please let <stable@xxxxxxxxxxxxxxx> know about it.

Subject: neigh: recompute reachabletime before returning from neigh_periodic_work()
From: Duan Jiong <duanj.fnst@xxxxxxxxxxxxxx>
[ Upstream commit feff9ab2e7fa773b6a3965f77375fe89f7fd85cf ]
If the neigh table's entries is less than gc_thresh1, the function
will return directly, and the reachabletime will not be recompute,
so the reachabletime can be guessed.
