NFS: Don't SIGBUS if nfs_vm_page_mkwrite races with a cache invalidation
In the case where we lock the page, and then find out that the page has been thrown out of the page cache, we should just return VM_FAULT_NOPAGE. This is what block_page_mkwrite() does in these situations. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Cc: stable@kernel.org
