3.5.7.17 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Stanislav Kinsbursky <[email protected]> commit 4f6bb246f69443549fbbd0f2abaf863243cb35e9 upstream. Not need to create pipes for dying client. So just skip them. Note: we can safely dereference the client structure, because notification caller is holding sn->pipefs_sb_lock.
