H A Dfile.cdiff bc4866b6e0b44f8ea0df22a16e5927714beb4983 Mon Oct 04 16:59:08 CDT 2010 Trond Myklebust <Trond.Myklebust@netapp.com> 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.
