+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()')
+
+Upstream-Status: Backport
