1Subject: [PATCH] Add missing rwlock_unlocks in xprt_register
2
3It looks like in b2c9430f46c4ac848957fb8adaac176a3f6ac03f when svc_run
4switched to poll, an early return was added, but the rwlock was not
5unlocked.
6
7I observed that rpcbind built against libtirpc-1.0.1 would handle only
8one request before hanging, and tracked it down to a missing
9rwlock_unlock here.
10
11Fixes: b2c9430f46c4 ('Use poll() instead of select() in svc_run()')

771+ * This file defines five types of data structures: singly-linked lists,
772+ * lists, simple queues, tail queues, and circular queues.
773+ *
774+ * A singly-linked list is headed by a single forward pointer. The
775+ * elements are singly linked for minimum space and pointer manipulation
776+ * overhead at the expense of O(n) removal for arbitrary elements. New
777+ * elements can be added to the list after an existing element or at the
778+ * head of the list. Elements being removed from the head of the list
779+ * should use the explicit macro for this purpose for optimum
780+ * efficiency. A singly-linked list may only be traversed in the forward
781+ * direction. Singly-linked lists are ideal for applications with large
782+ * datasets and few or no removals or for implementing a LIFO queue.
783+ *
784+ * A list is headed by a single forward pointer (or an array of forward
785+ * pointers for a hash table header). The elements are doubly linked
786+ * so that an arbitrary element can be removed without a need to
787+ * traverse the list. New elements can be added to the list before
788+ * or after an existing element or at the head of the list. A list
789+ * may only be traversed in the forward direction.
790+ *
791+ * A simple queue is headed by a pair of pointers, one the head of the
792+ * list and the other to the tail of the list. The elements are singly
793+ * linked to save space, so elements can only be removed from the
794+ * head of the list. New elements can be added to the list after
795+ * an existing element, at the head of the list, or at the end of the
796+ * list. A simple queue may only be traversed in the forward direction.
797+ *
798+ * A tail queue is headed by a pair of pointers, one to the head of the
799+ * list and the other to the tail of the list. The elements are doubly
800+ * linked so that an arbitrary element can be removed without a need to
801+ * traverse the list. New elements can be added to the list before or
802+ * after an existing element, at the head of the list, or at the end of
803+ * the list. A tail queue may be traversed in either direction.
804+ *
805+ * A circle queue is headed by a pair of pointers, one to the head of the
806+ * list and the other to the tail of the list. The elements are doubly
807+ * linked so that an arbitrary element can be removed without a need to
808+ * traverse the list. New elements can be added to the list before or after
809+ * an existing element, at the head of the list, or at the end of the list.
810+ * A circle queue may be traversed in either direction, but has a more
811+ * complex end of list detection.
812+ *
813+ * For details on the use of these macros, see the queue(3) manual page.
