13 years agoApply memory policies to top two highest zones when highest zone is ZONE_MOVABLE
Mel Gorman [Wed, 22 Aug 2007 21:02:05 +0000 (14:02 -0700)]
Apply memory policies to top two highest zones when highest zone is ZONE_MOVABLE

The NUMA layer only supports NUMA policies for the highest zone.  When
ZONE_MOVABLE is configured with kernelcore=, the the highest zone becomes
ZONE_MOVABLE.  The result is that policies are only applied to allocations
like anonymous pages and page cache allocated from ZONE_MOVABLE when the
zone is used.

This patch applies policies to the two highest zones when the highest zone
is ZONE_MOVABLE.  As ZONE_MOVABLE consists of pages from the highest "real"
zone, it's always functionally equivalent.

The patch has been tested on a variety of machines both NUMA and non-NUMA
covering x86, x86_64 and ppc64.  No abnormal results were seen in
kernbench, tbench, dbench or hackbench.  It passes regression tests from
the numactl package with and without kernelcore= once numactl tests are
patched to wait for vmstat counters to update.

akpm: this is the nasty hack to fix NUMA mempolicies in the presence of
ZONE_MOVABLE and kernelcore= in 2.6.23.  Christoph says "For .24 either merge
the mobility or get the other solution that Mel is working on.  That solution
would only use a single zonelist per node and filter on the fly.  That may
help performance and also help to make memory policies work better."

autofs4: deadlock during create

Due to inconsistent locking in the VFS between calls to lookup and
revalidate deadlock can occur in the automounter.

The inconsistency is that the directory inode mutex is held for both lookup
and revalidate calls when called via lookup_hash whereas it is held only
for lookup during a path walk.  Consequently, if the mutex is held during a
call to revalidate autofs4 can't release the mutex to callback the daemon
as it can't know whether it owns the mutex.

This situation happens when a process tries to create a directory within an
automount and a second process also tries to create the same directory
between the lookup and the mkdir.  Since the first process has dropped the
mutex for the daemon callback, the second process takes it during
revalidate leading to deadlock between the autofs daemon and the second
process when the daemon tries to create the mount point directory.

After spending quite a bit of time trying to resolve this on more than one
occassion, using rather complex and ulgy approaches, it turns out that just
delaying the hashing of the dentry until the create operation works fine.

signalfd: make it group-wide, fix posix-timers scheduling

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.

synchronous lumpy reclaim: wait for page writeback when directly reclaiming contiguous areas

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.

synchronous lumpy reclaim: ensure we count pages transitioning inactive via clear_active_flags

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.

This patch:

We are transitioning pages from active to inactive in clear_active_flags,
those need counting as PGDEACTIVATE vm events.

usb-storage: fix bugs in the disconnect pathway

This patch (as961) fixes a couple of bugs in the disconnect pathway of
usb-storage.

The first problem, which apparently has been around for a while
although nobody noticed it, shows up when an aborted command is still
pending when a disconnect occurs.  The SCSI error-handler will
continue to wait in command_abort() until the us->notify completion is
signalled.  Thus quiesce_and_remove_host() needs to signal it.

The second problem was introduced recently along with autosuspend
support.  Since usb_stor_scan_thread() now calls
usb_autopm_put_interface() before exiting, we can't simply leave the
scanning thread running after a disconnect; we must wait until the
thread exits.  This is solved by adding a new struct completion to the
private data structure.  Fortuitously, it allows the removal of the
rather clunky mechanism used in the past to insure that all threads
have finished before the module is unloaded.

USB: accept 1-byte Device Status replies, fixing some b0rken devices

Some devices have a bug which causes them to send a 1-byte reply to
Get-Device-Status requests instead of 2 bytes as required by the
spec.  This doesn't play well with autosuspend, since we look for a
valid status reply to make sure the device is still present when it
resumes.  Without both bytes, we assume the device has been
disconnected.

Lack of the second byte shouldn't matter much, since the spec requires
it always to be equal to 0.  Hence this patch (as959) causes
finish_port_resume() to accept a 1-byte reply as valid.
