Christoph Lameter [Wed, 1 Feb 2006 11:05:39 +0000]
[PATCH] Direct Migration V9: remove_from_swap() to remove swap ptes

Add remove_from_swap

remove_from_swap() allows the restoration of the pte entries that existed
before page migration occurred for anonymous pages by walking the reverse
maps.  This reduces swap use and establishes regular pte's without the need
for page faults.

[PATCH] Direct Migration V9: migrate_pages() extension

Add direct migration support with fall back to swap.

Direct migration support on top of the swap based page migration facility.

This allows the direct migration of anonymous pages and the migration of file
backed pages by dropping the associated buffers (requires writeout).

Fall back to swap out if necessary.

The patch is based on lots of patches from the hotplug project but the code
was restructured, documented and simplified as much as possible.

Note that an additional patch that defines the migrate_page() method for
filesystems is necessary in order to avoid writeback for anonymous and file
backed pages.

[PATCH] Direct Migration V9: PageSwapCache checks

Check for PageSwapCache after looking up and locking a swap page.

The page migration code may change a swap pte to point to a different page
under lock_page().

If that happens then the vm must retry the lookup operation in the swap space
to find the correct page number.  There are a couple of locations in the VM
where a lock_page() is done on a swap page.  In these locations we need to
check afterwards if the page was migrated.  If the page was migrated then the
old page that was looked up before was freed and no longer has the
PageSwapCache bit set.

[PATCH] Reclaim slab during zone reclaim

If large amounts of zone memory are used by empty slabs then zone_reclaim
becomes uneffective.  This patch shakes the slab a bit.

The problem with this patch is that the slab reclaim is not containable to a
zone.  Thus slab reclaim may affect the whole system and be extremely slow.
This also means that we cannot determine how many pages were freed in this
zone.  Thus we need to go off node for at least one allocation.

The functionality is disabled by default.

We could modify the shrinkers to take a zone parameter but that would be quite
invasive.  Better ideas are welcome.

13 years ago[PATCH] Zone reclaim: Allow modification of zone reclaim behavior
Christoph Lameter [Wed, 1 Feb 2006 11:05:34 +0000]
[PATCH] Zone reclaim: Allow modification of zone reclaim behavior

In some situations one may want zone_reclaim to behave differently.  For
example a process writing large amounts of memory will spew unto other nodes
to cache the writes if many pages in a zone become dirty.  This may impact the
performance of processes running on other nodes.

Allowing writes during reclaim puts a stop to that behavior and throttles the
process by restricting the pages to the local zone.

Similarly one may want to contain processes to local memory by enabling
regular swap behavior during zone_reclaim.  Off node memory allocation can
then be controlled through memory policies and cpusets.

Christoph Lameter [Wed, 1 Feb 2006 11:05:33 +0000]
[PATCH] zone_reclaim: configurable off node allocation period.

Currently the zone_reclaim code has a fixed window of 30 seconds of off node
allocations should a local zone have no unused pagecache pages left.  Reclaim
will be attempted again after this timeout period to avoid repeated useless
scans for memory.  This is also useful to established sufficiently large off
node allocation chunks to relieve the local node.

It may be beneficial to adjust that time period for some special situations.
For example if memory use was exceeding node capacity one may want to give up
for longer periods of time.  If memory spikes intermittendly then one may want
to shorten the time period to reduce the number of off node allocations.

This patch allows just that....

how far a new mapping may be allowed to extend the file.  But it's muddled:
each hugepage found covers HPAGE_SIZE, not PAGE_SIZE.  Once pages were

[PATCH] hrtimers: cleanups and simplifications

Clean up the interface to hrtimers by changing the init code to pass the mode
as well as the clock.  This allow the init code to select the correct base and

akpm@osdl.org [Wed, 1 Feb 2006 11:05:10 +0000]
[PATCH] hrtimers: fix posix-timer requeue race

From: Steven Rostedtrostedt@goodmis.org <rostedt@goodmis.org>

CPU0 expires a posix-timer and runs the callback function.  The signal is
queued.

After releasing the posix-timer lock and before returning to hrtimer_run_queue
CPU0 gets interrupted.  CPU1 delivers the queued signal and rearms the timer.
CPU0 comes back to hrtimer_run_queue and sets the timer state to expired.

The next modification of the timer can result in an oops, because the state
information is wrong.

Keep track of state = RUNNING and check if the state has been in the return
path of hrtimer_run_queue.  In case the state has been changed, ignore a
restart request and do not touch the state variable.

[PATCH] IPMI: remove invalid acpi register spacing check

At the 2.6.12 timeframe ipmi_si_intf.c was patched to provide default
register spacings in try_init_acpi() if the register spacing was set to
zero, similar to code in other routines.

Unfortunately, another patch was simultaneously added that exits early from
try_init_acpi() if the register spacings are set to zero, circumventing the
new defaults.  This patch removes the early exit code and some incorrect
comments that aren't present in other common code snippets.

[PATCH] device-mapper log bitset: fix endian

Clean up the code responsible for the on-disk mirror logs by using the
set_le_bit test_le_bit functions of ext2.  That makes the BE machines keep the
bitmap internally in LE order - it does mean you can't use any other type of
operations on the bitmap words but that looks to be OK in this instance.  The
efficiency tradeoff is very minimal as you would expect for something that
ext2 uses.

This allows us to remove bits_to_core(), bits_to_disk() and log->disk_bits.

Also increment the mirror log disk version transparently to avoid sharing with
older kernels that suffered from the 64-bit BE bug.

[PATCH] ide-scsi: fix for IDE probe/remove ops changes

Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but fails to
find any devices to bind to.  It also triggers a message "Driver 'ide-scsi'
needs updating - please use bus_type methods" from the driver core.

The IDE core in 2.6.16-rc1 changed the location of an IDE driver's
->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t
struct not in the gen_driver sub-struct.  drivers/ide/ was updated for this
change but ide-scsi.c wasn't.  Hence the breakage.

This patch repairs ide-scsi and also eliminates the driver core warning.

[PATCH] sound/ppc/pmac.c typo

In 2.6.16-rc1 there is a small typo introduced by the 'Remove device_node
addrs/n_addr' changes which prevents my Powerbook G4 sound from working:

Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 UTC).
snd: can't request rsrc  0 (Sound Control: 0x80000000:80004fff)
ALSA device list:
   No soundcards found.

The patch below fixes it.  Of course, the patch fixing the i2c issues
('i2c_smbus_write_i2c_block_data' patch) needs to be applied to in order
for the sound to completly work.

Miklos Szeredi [Wed, 1 Feb 2006 11:04:40 +0000]
[PATCH] fuse: fix async read for legacy filesystems

While asynchronous reads mean a performance improvement in most cases, if
the filesystem assumed that reads are synchronous, then async reads may
degrade performance (filesystem may receive reads out of order, which can
confuse it's own readahead logic).

With sshfs a 1.5 to 4 times slowdown can be measured.

There's also a need for userspace filesystems to know whether asynchronous
reads are supported by the kernel or not.

To achive these, negotiate in the INIT request whether async reads will be
used and the maximum readahead value.  Update interface version to 7.6

If userspace uses a version earlier than 7.6, then disable async reads, and
set maximum readahead value to the maximum read size, as done in previous
versions.

[PATCH] PCI Hotplug: PCI panic on dlpar add (add pci slot to running partition)

Removing and then adding a PCI slot to a running partition results in
a kernel panic. The current code attempts to add iospace for an entire
root bus, which is inappropriate, and silently fails.  When a pci device
tries to use the iospace, a page fault is taken, as the iospace had not
been mapped, and of course the page fault cannot be resolved.

This only occurs for PCI adapters using pio, which may be why it hadn't
been seen earlier (this seems to have been broken for a while).
This patch has survived testing of dozens of slot add and removes.
