+From 4f1503e84b2f7bd229a097335e52fb8203f5bb0b Mon Sep 17 00:00:00 2001
+From: Michael Forney <mforney at mforney.org>
+Date: Wed, 4 Nov 2015 13:58:06 -0500
+Subject: [PATCH] Add missing rwlock_unlocks in xprt_register
+
+It looks like in b2c9430f46c4ac848957fb8adaac176a3f6ac03f when svc_run
+switched to poll, an early return was added, but the rwlock was not
+unlocked.
+
+I observed that rpcbind built against libtirpc-1.0.1 would handle only
+one request before hanging, and tracked it down to a missing
+rwlock_unlock here.
+
+Fixes: b2c9430f46c4 ('Use poll() instead of select() in svc_run()')

+Subject: [PATCH] Add missing rwlock_unlocks in xprt_register
+
+It looks like in b2c9430f46c4ac848957fb8adaac176a3f6ac03f when svc_run
+switched to poll, an early return was added, but the rwlock was not
+unlocked.
+
+I observed that rpcbind built against libtirpc-1.0.1 would handle only
+one request before hanging, and tracked it down to a missing
+rwlock_unlock here.
+
+Fixes: b2c9430f46c4 ('Use poll() instead of select() in svc_run()')
