Hi Julia,

Thanks for pointing this out! Given that the 'then' clause of the if
statement already calls nfs_setsecurity before unlocking the inode, I
suspect that the above _should_ really be part of the 'else' clause.

That said, I can't see that calling nfs_setsecurity twice on the inode
can cause any unintended side-effects, so I suggest that we rather queue
the patch up for inclusion in 3.12.
Steve and Dave, any comments?
