svc_xprt_received must be called when ->xpo_recvfrom has finished receiving a message, so that the XPT_BUSY flag will be cleared and if necessary, requeued for further work. This call is currently made in each ->xpo_recvfrom function, often from multiple different points. In each case it is the earliest point on a particular path where it is known that the protection provided by XPT_BUSY is no longer needed. However there are (still) some error paths which do not call svc_xprt_received, and requiring each ->xpo_recvfrom to make the call does not encourage robustness. So: move the svc_xprt_received call to be made just after the call to ->xpo_recvfrom(), and move it of the various ->xpo_recvfrom methods. This means that it may not be called at the earliest possible instant, but this is unlikely to be a measurable performance issue. Note that there are still other calls to svc_xprt_received as it is also needed when an xprt is newly created. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J.
