Subject[PATCH 4.10 141/167] Revert "NFSv4.1: Handle NFS4ERR_BADSESSION/NFS4ERR_DEADSESSION replies to OP_SEQUENCE"
Date
4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Trond Myklebust <trond.myklebust@primarydata.com>

commit a5e14c9376871ee74fe93fdcb380c5d54eaa2d43 upstream.

This reverts commit 2cf10cdd486c362f983abdce00dc1127e8ab8c59.

The patch has been seen to cause excessive looping.
