Gluster users - Jul 2014 - Cannot rename files with root squashing and r-x folder group permissions

Hi All,
After a recent update to gluster 3.5 we are having some issues renaming
files when root squashing is enabled and the folder group permissions are
not set to write.

For example if I create a folder with the following permissions
$ mkdir test
$ chmod g-w test
$ ls -l
drwxr-xr-x  2 dave dave  22 Jul 14 17:16 test

When I create a file *within* this folder, and try to rename it I get a
file permissions error.

$ cd test
$ touch asdf
$ mv asdf asdf2
mv: cannot move ?asdf? to ?asdf2?: Permission denied

A strace on the mv command reveals the rename system call fails with:
rename("asdf", "asdf2") = -1 EACCES (Permission denied)

However I can copy the file and delete the old one fine.

If I either disable gluster root squashing, or change the test_dir folder
group permission to write then I can rename the file without any problems.

System details are:
Arch linux
System umask is set to 002
Distributed volume, 3 peers, 1 brick per peer.

Any help is much appreciated!
Dave
