nfsd: wrong index used in inner loop
commit 5a02ab7c3c4580f94d13c683721039855b67cda6 upstream. We must not use dummy for index. After the first index, READ32(dummy) will change dummy!!!! Signed-off-by: Mi Jinlong <mijinlong@cn.fujitsu.com> [bfields@redhat.com: Trond points out READ_BUF alone is sufficient.] Signed-off-by: J. Bruce Fields <bfields@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
