Subject: SUNRPC: Clear the request rq_bytes_sent field in xprt_release_write
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ee071eff0f1afafa9917254a6e4ee19d28085f1d;p=linux-beck.git

SUNRPC: Clear the request rq_bytes_sent field in xprt_release_write

Otherwise the tests of req->rq_bytes_sent in xprt_prepare_transmit
will fail if we're dealing with a resend.
