Subject: SUNRPC: Clear rq_xid when receiving a new RPC Call
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=695bc1f32c6bc806218b322096b23dfd601e59ca;p=linux.git

SUNRPC: Clear rq_xid when receiving a new RPC Call

This is an eye-catcher for tracepoints that record the XID: it means
svc_rqst() has not received a full RPC Call with an XID yet.
