+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

++ * This file defines five types of data structures: singly-linked lists,
++ * lists, simple queues, tail queues, and circular queues.
++ *
++ * A singly-linked list is headed by a single forward pointer. The
++ * elements are singly linked for minimum space and pointer manipulation
++ * overhead at the expense of O(n) removal for arbitrary elements. New
++ * elements can be added to the list after an existing element or at the
++ * head of the list.  Elements being removed from the head of the list
++ * should use the explicit macro for this purpose for optimum
++ * efficiency. A singly-linked list may only be traversed in the forward
++ * direction.  Singly-linked lists are ideal for applications with large
++ * datasets and few or no removals or for implementing a LIFO queue.
++ *
++ * A list is headed by a single forward pointer (or an array of forward
++ * pointers for a hash table header). The elements are doubly linked
++ * so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before
++ * or after an existing element or at the head of the list. A list
++ * may only be traversed in the forward direction.
++ *
++ * A simple queue is headed by a pair of pointers, one the head of the
++ * list and the other to the tail of the list. The elements are singly
++ * linked to save space, so elements can only be removed from the
++ * head of the list. New elements can be added to the list after
++ * an existing element, at the head of the list, or at the end of the
++ * list. A simple queue may only be traversed in the forward direction.
++ *
++ * A tail queue is headed by a pair of pointers, one to the head of the
++ * list and the other to the tail of the list. The elements are doubly
++ * linked so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before or
++ * after an existing element, at the head of the list, or at the end of
++ * the list. A tail queue may be traversed in either direction.
++ *
++ * A circle queue is headed by a pair of pointers, one to the head of the
++ * list and the other to the tail of the list. The elements are doubly
++ * linked so that an arbitrary element can be removed without a need to
++ * traverse the list. New elements can be added to the list before or after
++ * an existing element, at the head of the list, or at the end of the list.
++ * A circle queue may be traversed in either direction, but has a more
++ * complex end of list detection.
++ *
++ * For details on the use of these macros, see the queue(3) manual page.

++
++/*
++ * Include the definition of NULL only on NetBSD because sys/null.h

++ * The caveat is that on other systems some other header
++ * must provide NULL before the macros can be used.
