Will this bug be fixed in next kernel update for trusty 14.04?

We have the problem that nfs4-id-mapping didn't work in 14.04 with rpc.idmapd. Sometimes the UIDs are listet as 4294967294.

After rebuilding kernel 3.13.0-32 with build option CONFIG_KEYS_DEBUG_PROC_KEY and using the new mapping method with /proc/keys the problem was fixed. (Had to increase kernel.keys.root_maxkeys and kernel.keys.maxkeys).

I had the same problem and have tried the same remedy, increasing the parameters and rebuld kernel
with CONFIG_KEYS_DEBUG_PROC_KEY=y
I did this with 3.13.0-34 on a ubuntu 14.04 client which was running already this kernel in which it was
not fixed.

When can we expect this to be present in a trusty kernel update ?
We are experiencing a lot of trouble with this since we are migrating more machines
to 14.04.
We had and still have the same problem but a lot less frequently on 12.04 clients.
Is the same fix expected to work ?

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I have tested the proposed kernel and it works, /proc/keys gets filled and
nfsidmap -c
now works without complaint
