+INFINIBAND MIDLAYER LOCKING
+
+  This guide is an attempt to make explicit the locking assumptions
+  made by the InfiniBand midlayer.  It describes the requirements on
+  both low-level drivers that sit below the midlayer and upper level
+  protocols that use the midlayer.
+
+Sleeping and interrupt context
+
+  With the following exceptions, a low-level driver implementation of
+  all of the methods in struct ib_device may sleep.  The exceptions
+  are any methods from the list:
+
+    create_ah
+    modify_ah
+    query_ah
+    destroy_ah
+    bind_mw
+    post_send
+    post_recv
+    poll_cq
+    req_notify_cq
+    map_phys_fmr
+
+  which may not sleep and must be callable from any context.
+
+  The corresponding functions exported to upper level protocol
+  consumers:
+
+    ib_create_ah
+    ib_modify_ah
+    ib_query_ah
+    ib_destroy_ah
+    ib_bind_mw
+    ib_post_send
+    ib_post_recv
+    ib_req_notify_cq
+    ib_map_phys_fmr
+
+  are therefore safe to call from any context.
+
+  In addition, the function
+
+    ib_dispatch_event
+
+  used by low-level drivers to dispatch asynchronous events through
+  the midlayer is also safe to call from any context.
+
+Reentrancy
+
+  All of the methods in struct ib_device exported by a low-level
+  driver must be fully reentrant.  The low-level driver is required to
+  perform all synchronization necessary to maintain consistency, even
+  if multiple function calls using the same object are run
+  simultaneously.
+
+  The IB midlayer does not perform any serialization of function calls.
+
+  Because low-level drivers are reentrant, upper level protocol
+  consumers are not required to perform any serialization.  However,
+  some serialization may be required to get sensible results.  For
+  example, a consumer may safely call ib_poll_cq() on multiple CPUs
+  simultaneously.  However, the ordering of the work completion
+  information between different calls of ib_poll_cq() is not defined.
+
+Callbacks
+
+  A low-level driver must not perform a callback directly from the
+  same callchain as an ib_device method call.  For example, it is not
+  allowed for a low-level driver to call a consumer's completion event
+  handler directly from its post_send method.  Instead, the low-level
+  driver should defer this callback by, for example, scheduling a
+  tasklet to perform the callback.
+
+  The low-level driver is responsible for ensuring that multiple
+  completion event handlers for the same CQ are not called
+  simultaneously.  The driver must guarantee that only one CQ event
+  handler for a given CQ is running at a time.  In other words, the
+  following situation is not allowed:
+
+        CPU1                                    CPU2
+
+  low-level driver ->
+    consumer CQ event callback:
+      /* ... */
+      ib_req_notify_cq(cq, ...);
+                                        low-level driver ->
+      /* ... */                           consumer CQ event callback:
+                                            /* ... */
+      return from CQ event handler
+
+  The context in which completion event and asynchronous event
+  callbacks run is not defined.  Depending on the low-level driver, it
+  may be process context, softirq context, or interrupt context.
+  Upper level protocol consumers may not sleep in a callback.
+
+Hot-plug
+
+  A low-level driver announces that a device is ready for use by
+  consumers when it calls ib_register_device(), all initialization
+  must be complete before this call.  The device must remain usable
+  until the driver's call to ib_unregister_device() has returned.
+
+  A low-level driver must call ib_register_device() and
+  ib_unregister_device() from process context.  It must not hold any
+  semaphores that could cause deadlock if a consumer calls back into
+  the driver across these calls.
+
+  An upper level protocol consumer may begin using an IB device as
+  soon as the add method of its struct ib_client is called for that
+  device.  A consumer must finish all cleanup and free all resources
+  relating to a device before returning from the remove method.
+
+  A consumer is permitted to sleep in its add and remove methods.

+Rules on what kind of patches are accepted, and what ones are not, into
+the "-stable" tree:
+
+ - It must be obviously correct and tested.
+ - It can not bigger than 100 lines, with context.
+ - It must fix only one thing.
+ - It must fix a real bug that bothers people (not a, "This could be a
+   problem..." type thing.)
+ - It must fix a problem that causes a build error (but not for things
+   marked CONFIG_BROKEN), an oops, a hang, data corruption, a real
+   security issue, or some "oh, that's not good" issue.  In short,
+   something critical.
+ - No "theoretical race condition" issues, unless an explanation of how
+   the race can be exploited.
+ - It can not contain any "trivial" fixes in it (spelling changes,
+   whitespace cleanups, etc.)
+ - It must be accepted by the relevant subsystem maintainer.
+ - It must follow Documentation/SubmittingPatches rules.
+
+
+Procedure for submitting patches to the -stable tree:
+
+ - Send the patch, after verifying that it follows the above rules, to
+   stable@kernel.org.
+ - The sender will receive an ack when the patch has been accepted into
+   the queue, or a nak if the patch is rejected.  This response might
+   take a few days, according to the developer's schedules.
+ - If accepted, the patch will be added to the -stable queue, for review
+   by other developers.
+ - Security patches should not be sent to this alias, but instead to the
+   documented security@kernel.org.
+
+
+Review cycle:
+
+ - When the -stable maintainers decide for a review cycle, the patches
+   will be sent to the review committee, and the maintainer of the
+   affected area of the patch (unless the submitter is the maintainer of
+   the area) and CC: to the linux-kernel mailing list.
+ - The review committee has 48 hours in which to ack or nak the patch.
+ - If the patch is rejected by a member of the committee, or linux-kernel
+   members object to the patch, bringing up issues that the maintainers
+   and members did not realize, the patch will be dropped from the
+   queue.
+ - At the end of the review cycle, the acked patches will be added to
+   the latest -stable release, and a new -stable release will happen.
+ - Security patches will be accepted into the -stable tree directly from
+   the security kernel team, and not go through the normal review cycle.
+   Contact the kernel security team for more details on this procedure.
+
+
+Review committe:
+
+ - This will be made up of a number of kernel developers who have
+   volunteered for this task, and a few that haven't.
