Merge tag 'io_uring-7.3-20261002' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linuxgrafted

Pull io_uring fixes from Jens Axboe:

 - Fix a task_work add use-after-free with SQPOLL.

   The sqpoll thread could pop and complete the last request while
   io_req_normal_work_add() was still looking at them after the mpscq
   push.

   Use the same approach as DEFER_TASKRUN to protect from that, holding
   an RCU read lock across the add, and have exit wait for an RCU grace
   period for SQPOLL rings as well.

 - CQE32 ring fixes: correct the free entry check for 32b CQEs, zero the
   big_cqe for aux CQEs, and only post the dummy skip CQE on CQE_MIXED
   rings

 - Mark the source filter table as COW when cloning bpf filters, so
   registering another filter on the source doesn't modify the shared
   table in place

 - Initialize the task context before running the BPF loop

 - Requeue zcrx multishot receives stopped by a local resource

 - End a TX_TIMESTAMP multishot cmd when the CQ is full (lollipopkit)

+	  Link Access Procedure, Balanced (LAPB) is the data link layer (i.e.
+	  the lower) part of the X.25 protocol. It offers a reliable
+	  connection service to exchange data frames with one other host, and
+	  it is used to transport higher level protocols (mostly X.25 Packet
+	  Layer, the higher part of X.25, but others are possible as well).
+	  Usually, LAPB is used with specialized X.21 network cards, but Linux
+	  currently supports LAPB only over Ethernet connections. If you want
+	  to use LAPB connections over Ethernet, say Y here and to "LAPB over
+	  Ethernet driver" below. Read
+	  <file:Documentation/networking/lapb-module.rst> for technical
+	  details.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called lapb.  If unsure, say N.
