Author: rmacklem Date: Sun Apr 9 21:06:21 2017 New Revision: 316666 URL: https://svnweb.freebsd.org/changeset/base/316666 Log: Fix the NFSv4.1 client for NFSERR_BADSESSION recovery via ReclaimComplete. For the ReclaimComplete operation, the RPC layer should not loop on NFSERR_BADSESSION. If it does, the recovery thread (nfscl) can get stuck looping and will not do a recovery. This patch fixes it so it does not loop. This bug only affects NFSv4.1 and only when a server reboots.
