[PATCH v2 1/2] NFSv4: Handle fatal ENETDOWN and ENETUNREACH errors

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

Ensure that the NFSv4 error handling code recognises the
RPC_TASK_NETUNREACH_FATAL flag, and handles the ENETDOWN and ENETUNREACH
errors accordingly.
