3.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Trond Myklebust <Trond.Myklebust@xxxxxxxxxx> commit d49f042aeec99c5f87160bb52dd52088b1051311 upstream. Currently, if the call to nfs_refresh_inode fails, then we end up leaking a reference count, due to the call to nfs4_get_open_state. While we're at it, replace nfs4_get_open_state with a simple call to atomic_inc(); there is no need to do a full lookup of the struct nfs_state since it is passed as an argument in the struct nfs4_opendata, and is already assigned to the variable 'state'.
