 CONFIG_RCU_TRACE debugfs Files and Formats
 
 
-The rcupreempt and rcutree implementations of RCU provide debugfs trace
-output that summarizes counters and state.  This information is useful for
-debugging RCU itself, and can sometimes also help to debug abuses of RCU.
-Note that the rcuclassic implementation of RCU does not provide debugfs
-trace output.
-
-The following sections describe the debugfs files and formats for
-preemptable RCU (rcupreempt) and hierarchical RCU (rcutree).
-
-
-Preemptable RCU debugfs Files and Formats
-
-This implementation of RCU provides three debugfs files under the
-top-level directory RCU: rcu/rcuctrs (which displays the per-CPU
-counters used by preemptable RCU) rcu/rcugp (which displays grace-period
-counters), and rcu/rcustats (which internal counters for debugging RCU).
-
-The output of "cat rcu/rcuctrs" looks as follows:
-
-CPU last cur F M
-  0    5  -5 0 0
-  1   -1   0 0 0
-  2    0   1 0 0
-  3    0   1 0 0
-  4    0   1 0 0
-  5    0   1 0 0
-  6    0   2 0 0
-  7    0  -1 0 0
-  8    0   1 0 0
-ggp = 26226, state = waitzero
-
-The per-CPU fields are as follows:
-
-o	"CPU" gives the CPU number.  Offline CPUs are not displayed.
-
-o	"last" gives the value of the counter that is being decremented
-	for the current grace period phase.  In the example above,
-	the counters sum to 4, indicating that there are still four
-	RCU read-side critical sections still running that started
-	before the last counter flip.
-
-o	"cur" gives the value of the counter that is currently being
-	both incremented (by rcu_read_lock()) and decremented (by
-	rcu_read_unlock()).  In the example above, the counters sum to
-	1, indicating that there is only one RCU read-side critical section
-	still running that started after the last counter flip.
-
-o	"F" indicates whether RCU is waiting for this CPU to acknowledge
-	a counter flip.  In the above example, RCU is not waiting on any,
-	which is consistent with the state being "waitzero" rather than
-	"waitack".
-
-o	"M" indicates whether RCU is waiting for this CPU to execute a
-	memory barrier.  In the above example, RCU is not waiting on any,
-	which is consistent with the state being "waitzero" rather than
-	"waitmb".
-
-o	"ggp" is the global grace-period counter.
-
-o	"state" is the RCU state, which can be one of the following:
-
-	o	"idle": there is no grace period in progress.
-
-	o	"waitack": RCU just incremented the global grace-period
-		counter, which has the effect of reversing the roles of
-		the "last" and "cur" counters above, and is waiting for
-		all the CPUs to acknowledge the flip.  Once the flip has
-		been acknowledged, CPUs will no longer be incrementing
-		what are now the "last" counters, so that their sum will
-		decrease monotonically down to zero.
-
-	o	"waitzero": RCU is waiting for the sum of the "last" counters
-		to decrease to zero.
-
-	o	"waitmb": RCU is waiting for each CPU to execute a memory
-		barrier, which ensures that instructions from a given CPU's
-		last RCU read-side critical section cannot be reordered
-		with instructions following the memory-barrier instruction.
-
-The output of "cat rcu/rcugp" looks as follows:
-
-oldggp=48870  newggp=48873
-
-Note that reading from this file provokes a synchronize_rcu().  The
-"oldggp" value is that of "ggp" from rcu/rcuctrs above, taken before
-executing the synchronize_rcu(), and the "newggp" value is also the
-"ggp" value, but taken after the synchronize_rcu() command returns.
-
-
-The output of "cat rcu/rcugp" looks as follows:
-
-na=1337955 nl=40 wa=1337915 wl=44 da=1337871 dl=0 dr=1337871 di=1337871
-1=50989 e1=6138 i1=49722 ie1=82 g1=49640 a1=315203 ae1=265563 a2=49640
-z1=1401244 ze1=1351605 z2=49639 m1=5661253 me1=5611614 m2=49639
-
-These are counters tracking internal preemptable-RCU events, however,
-some of them may be useful for debugging algorithms using RCU.  In
-particular, the "nl", "wl", and "dl" values track the number of RCU
-callbacks in various states.  The fields are as follows:
-
-o	"na" is the total number of RCU callbacks that have been enqueued
-	since boot.
-
-o	"nl" is the number of RCU callbacks waiting for the previous
-	grace period to end so that they can start waiting on the next
-	grace period.
-
-o	"wa" is the total number of RCU callbacks that have started waiting
-	for a grace period since boot.  "na" should be roughly equal to
-	"nl" plus "wa".
-
-o	"wl" is the number of RCU callbacks currently waiting for their
-	grace period to end.
-
-o	"da" is the total number of RCU callbacks whose grace periods
-	have completed since boot.  "wa" should be roughly equal to
-	"wl" plus "da".
-
-o	"dr" is the total number of RCU callbacks that have been removed
-	from the list of callbacks ready to invoke.  "dr" should be roughly
-	equal to "da".
-
-o	"di" is the total number of RCU callbacks that have been invoked
-	since boot.  "di" should be roughly equal to "da", though some
-	early versions of preemptable RCU had a bug so that only the
-	last CPU's count of invocations was displayed, rather than the
-	sum of all CPU's counts.
-
-o	"1" is the number of calls to rcu_try_flip().  This should be
-	roughly equal to the sum of "e1", "i1", "a1", "z1", and "m1"
-	described below.  In other words, the number of times that
-	the state machine is visited should be equal to the sum of the
-	number of times that each state is visited plus the number of
-	times that the state-machine lock acquisition failed.
-
-o	"e1" is the number of times that rcu_try_flip() was unable to
-	acquire the fliplock.
-
-o	"i1" is the number of calls to rcu_try_flip_idle().
-
-o	"ie1" is the number of times rcu_try_flip_idle() exited early
-	due to the calling CPU having no work for RCU.
-
-o	"g1" is the number of times that rcu_try_flip_idle() decided
-	to start a new grace period.  "i1" should be roughly equal to
-	"ie1" plus "g1".
-
-o	"a1" is the number of calls to rcu_try_flip_waitack().
-
-o	"ae1" is the number of times that rcu_try_flip_waitack() found
-	that at least one CPU had not yet acknowledge the new grace period
-	(AKA "counter flip").
-
-o	"a2" is the number of time rcu_try_flip_waitack() found that
-	all CPUs had acknowledged.  "a1" should be roughly equal to
-	"ae1" plus "a2".  (This particular output was collected on
-	a 128-CPU machine, hence the smaller-than-usual fraction of
-	calls to rcu_try_flip_waitack() finding all CPUs having already
-	acknowledged.)
-
-o	"z1" is the number of calls to rcu_try_flip_waitzero().
-
-o	"ze1" is the number of times that rcu_try_flip_waitzero() found
-	that not all of the old RCU read-side critical sections had
-	completed.
-
-o	"z2" is the number of times that rcu_try_flip_waitzero() finds
-	the sum of the counters equal to zero, in other words, that
-	all of the old RCU read-side critical sections had completed.
-	The value of "z1" should be roughly equal to "ze1" plus
-	"z2".
-
-o	"m1" is the number of calls to rcu_try_flip_waitmb().
-
-o	"me1" is the number of times that rcu_try_flip_waitmb() finds
-	that at least one CPU has not yet executed a memory barrier.
-
-o	"m2" is the number of times that rcu_try_flip_waitmb() finds that
-	all CPUs have executed a memory barrier.

+================
+HELPER FUNCTIONS
+================
+
+The slow-work facility provides a function by which it can be determined
+whether or not an item is queued for later execution:
+
+	bool queued = slow_work_is_queued(struct slow_work *work);
+
+If it returns false, then the item is not on the queue (it may be executing
+with a requeue pending).  This can be used to work out whether an item on which
+another depends is on the queue, thus allowing a dependent item to be queued
+after it.
+
+If the above shows an item on which another depends not to be queued, then the
+owner of the dependent item might need to wait.  However, to avoid locking up
+the threads unnecessarily be sleeping in them, it can make sense under some
+circumstances to return the work item to the queue, thus deferring it until
+some other items have had a chance to make use of the yielded thread.
+
+To yield a thread and defer an item, the work function should simply enqueue
+the work item again and return.  However, this doesn't work if there's nothing
+actually on the queue, as the thread just vacated will jump straight back into
+the item's work function, thus busy waiting on a CPU.
+
+Instead, the item should use the thread to wait for the dependency to go away,
+but rather than using schedule() or schedule_timeout() to sleep, it should use
+the following function:
+
+	bool requeue = slow_work_sleep_till_thread_needed(
+			struct slow_work *work,
+			signed long *_timeout);
+
+This will add a second wait and then sleep, such that it will be woken up if
+either something appears on the queue that could usefully make use of the
+thread - and behind which this item can be queued, or if the event the caller
+set up to wait for happens.  True will be returned if something else appeared
+on the queue and this work function should perhaps return, of false if
+something else woke it up.  The timeout is as for schedule_timeout().
+
+For example:
+
+	wq = bit_waitqueue(&my_flags, MY_BIT);
+	init_wait(&wait);
+	requeue = false;
+	do {
+		prepare_to_wait(wq, &wait, TASK_UNINTERRUPTIBLE);
+		if (!test_bit(MY_BIT, &my_flags))
+			break;
+		requeue = slow_work_sleep_till_thread_needed(&my_work,
+							     &timeout);
+	} while (timeout > 0 && !requeue);
+	finish_wait(wq, &wait);
+	if (!test_bit(MY_BIT, &my_flags)
+		goto do_my_thing;
+	if (requeue)
+		return; // to slow_work

+Version 1.61
+------------
+Fix append problem to Samba servers (files opened with O_APPEND could
+have duplicated data). Fix oops in cifs_lookup. Workaround problem
+mounting to OS/400 Netserve. Fix oops in cifs_get_tcp_session.
+Disable use of server inode numbers when server only
+partially supports them (e.g. for one server querying inode numbers on
+FindFirst fails but QPathInfo queries works).
+
 Version 1.60
 -------------
 Fix memory leak in reconnect.  Fix oops in DFS mount error path.
