6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Olga Kornievskaia <kolga@xxxxxxxxxx>
[ Upstream commit 5cc7688bae7f0757c39c1d3dfdd827b724061067 ]
If the client is doing pnfs IO and Kerberos is configured and EXCHANGEID
successfully negotiated SP4_MACH_CRED and WRITE/COMMIT are on the
list of state protected operations, then we need to make sure to
choose the DS's rpc_client structure instead of the MDS's one.
Fixes: fb91fb0ee7b2 ("NFS: Move call to nfs4_state_protect_write() to nfs4_write_setup()")
