nfsd4: reserve space before inlining 0-copy pages Once we've included page-cache pages in the encoding it's difficult to remove them and restart encoding. (xdr_truncate_encode doesn't handle that case.) So, make sure we'll have adequate space to finish the operation first. For now COMPOUND_SLACK_SPACE checks should prevent this case happening, but we want to remove those checks. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
