Subject: NFSv4.1: Fix the handling of NFS4ERR_SEQ_MISORDERED errors
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=444f72fe7e7b5f4db34cee933fa3546ebb8e9122;p=mv-sheeva.git

NFSv4.1: Fix the handling of NFS4ERR_SEQ_MISORDERED errors

Currently, the call to nfs4_schedule_session_recovery() will actually just
result in a test of the lease when what we really want is to force a
session reset.
