Subject: SUNRPC: ECONNRESET might require a rebind
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4b09ca1508a60be30b2e3940264e93d7aeb5c97e;p=linux.git

SUNRPC: ECONNRESET might require a rebind

If connect() is returning ECONNRESET, it usually means that nothing is
listening on that port. If so, a rebind might be required in order to
obtain the new port on which the RPC service is listening.

Fixes: fd01b2597941 ("SUNRPC: ECONNREFUSED should cause a rebind.")
