Hi Greg,
Looks like this fixes an issue on 2.6.32.17 -
https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/562913 . The
patch has hit mainline (as of 2.6.33, in commit
d327cf7449e6fd5cbac784c641770e9366faa386), but has missed stable.
Bruce - let me know if there's any reason this shouldn't go in.
Please consider for inclusion in the 2.6.32.y stable series.
Regards,
Jeremy

Subject: [PATCH] nfs: fix acl decoding
Commit 28f566942c6b1d929f5e240e69e7081b77b238d3 "NFS: use dynamically
computed compound_hdr.replen for xdr_inline_pages offset" accidentally
changed the amount of space to allow for the acl reply, resulting in an
IO error on attempts to get an acl.
