Thanks.

Without this patch (commit 2a04cd4c7 aka v2.6.33-rc6~29^2~33), Mason
(cc-ed) is not able to use appletalk[1]:

| With Linux 2.6.32 as supplied with Debian Squeeze, Netatalk is unable
| to thrive. Connections made to afpd will open, but attempting to transfer
| files will take a very long time and/or eventually time out.
|
| I've noted this with both Netatalk as supplied with Squeeze and with
| Netatalk 2.2.1 built from the Wheezy source package, which I evidently
| need for AFP 3 support.
|
| Installing Linux 3.2 from backports, with no other changes to the system,
| allows afpd to work correctly.

Ben sent a copy of this patch to try against 2.6.32.y and it worked.
Would it be possible to include this in the 2.6.32.y-longterm tree?

Sincerely,
Jonathan
