The previous patch which limited the number of sectors in a single request
to a COWed device was correct in concept, but the limit was implemented in
the wrong place.

By putting it in ubd_add, it covered the cases where the COWing was
specified on the command line.  However, when the command line only has the
COW file specified, the fact that it's a COW file isn't known until it's
opened, so the limit is missed in these cases.

This patch moves the sector limit from ubd_add to ubd_open_dev.

Commit 17571284 was slightly bad.  If an array
has a write-intent bitmap, and you remove a drive, then readd it, only the
changed parts should be resynced.  However after the above commit, this only
works if the array has not been shut down and restarted.

This is because it sets 'fullsync' at little more often than it should.  This

It seems a simple mistake was made when converting follow_hugetlb_page()
over to the VM_FAULT flags bitmasks (in "mm: fault feedback #2", commit

By using the wrong bitmask, hugetlb_fault() failures are not being

This will avoid cache misses that happen while accessing slabp (which is

With this patch any thread can dequeue its own private signals via signalfd,
even if it was created by another sub-thread.

To do so, we pass "current" to dequeue_signal() if the caller is from the same
thread group. This also fixes the scheduling of posix timers broken by the
previous patch.

If the caller doesn't belong to this thread group, we can't handle __SI_TIMER
case properly anyway. Perhaps we should forbid the cross-process signalfd usage
and convert ctx->tsk to ctx->sighand.

dequeue_signal:

		spin_unlock(&tsk->sighand->siglock);
		do_schedule_next_timer(info);
		spin_lock(&tsk->sighand->siglock);
	}

Unless tsk == curent, this is absolutely unsafe: nothing prevents tsk from
exiting. If signalfd was passed to another process, do_schedule_next_timer()
is just wrong.

Add yet another "tsk == current" check into dequeue_signal().

This patch fixes an oopsable bug, but breaks the scheduling of posix timers
if the shared __SI_TIMER signal was fetched via signalfd attached to another
sub-thread. Mostly fixed by the next patch.

sys_timer_create() sets ->it_process and unlocks ->siglock, then checks
tmr->it_sigev_notify to define if get_task_struct() is needed.

We already passed ->it_id to the caller, another thread can delete this timer
and free its memory in between.

As a minimal fix, move this code under ->siglock, sys_timer_delete() takes it
too before calling release_posix_timer().  A proper serialization would be to
take ->it_lock, we add a partly initialized timer on posix_timers_id, not

timer_delete does:
	lock_timer();
	timer->it_process = NULL;
	unlock_timer();
	release_posix_timer();

timer->it_process is checked in lock_timer() to prevent access to a
timer, which is on the way to be deleted, but the check happens after
idr_lock is dropped. This allows release_posix_timer() to delete the
timer before the lock code can check the timer:

  CPU 0				CPU 1

  lock_timer();
  timer->it_process = NULL;
  unlock_timer();
				lock_timer()
					spin_lock(idr_lock);

The new exec code inserts an accounted vma into an mm struct which is not

that this does not happen as does the security code.

As the correct mm is known we pass the mm to the security method and the
helper function.  A new security test is added for the case where we need
to pass the mm and the existing one is modified to pass current->mm to
avoid the need to change large amounts of code.

Lumpy reclaim works by selecting a lead page from the LRU list and then
selecting pages for reclaim from the order-aligned area of pages.  In the
situation were all pages in that region are inactive and not referenced by any
process over time, it works well.

In the situation where there is even light load on the system, the pages may
not free quickly.  Out of a area of 1024 pages, maybe only 950 of them are
freed when the allocation attempt occurs because lumpy reclaim returned early.
 This patch alters the behaviour of direct reclaim for large contiguous
blocks.

The first attempt to call shrink_page_list() is asynchronous but if it fails,
the pages are submitted a second time and the calling process waits for the IO
to complete.  This may stall allocators waiting for contiguous memory but that
should be expected behaviour for high-order users.  It is preferable behaviour
to potentially queueing unnecessary areas for IO.  Note that kswapd will not
stall in this fashion.

As pointed out by Mel when reclaim is applied at higher orders a significant
amount of IO may be started.  As this takes finite time to drain reclaim will
consider more areas than ultimatly needed to satisfy the request.  This leads
to more reclaim than strictly required and reduced success rates.

I was able to confirm Mel's test results on systems locally.  These show that
even under light load the success rates drop off far more than expected.
Testing with a modified version of his patch (which follows) I was able to
allocate almost all of ZONE_MOVABLE with a near idle system.  I ran 5 test
passes sequentially following system boot (the system has 29 hugepages in
ZONE_MOVABLE):

  2.6.23-rc1              11  8  6  7  7
  sync_lumpy              28 28 29 29 26

These show that although hugely better than the near 0% success normally
expected we can only allocate about a 1/4 of the zone.  Using synchronous
reclaim for these allocations we get close to 100% as expected.

I have also run our standard high order tests and these show no regressions in
allocation success rates at rest, and some significant improvements under
load.

lsr is read so they can be handled later in the receive routine.  Save the

Also, clear the stored bits and clear the interrupt registers before

The uart_set_termios() function will bail out early without bothering to
touch the hardware, if it decides that nothing "relevant" has changed.
Unfortunately, its idea of "relevant" doesn't include c_[io]speed.  So if
the baud rate bits are BOTHER and you just change the speed, the change
gets optimised away.

This patch makes it ignore the old Bfoo bits in c_cflag and just check
whether c_ispeed and c_ospeed have changed.  Those integers are always set

	kernel BUG at /home/apw/git/linux-2.6/mm/page_alloc.c:456!

This occurs because the section to node id mapping is not being
setup correctly during init under SPARSEMEM_STATIC, leading to an
attempt to free pages from all nodes into the zones on node 0.

When the zone_table[] was removed in the following commit, a new
section to node mapping table was introduced:

    commit 89689ae7
    [PATCH] Get rid of zone_table[]

That conversion inadvertantly only initialised the node mapping in
SPARSEMEM_EXTREME.  Ensure we initialise the node mapping in
