A large number of lost ticks can cause an overadjustment of the clock. To compensate for this we look at the current error and the larger the error already is the more careful we are at adjusting the error. As small extra fix reset the error when the clock is set. Signed-off-by:

It turns out that there is a way to build a kernel with NUMA and no SMP. In that case we are missing one definition __inc_zone_state. Provide that missing __inc_zone_state. (akpm: NUMA && !SMP sounds odd, but I am told "But there is the concept of cpuless nodes. A NUMA system without SMP has a single processor but multiple memory nodes. This used to work before on IA64 (wasn't aware of it, never seen anyone with this kind of thing).") Acked-by:

Daniel Ritz <daniel.ritz-ml@swissonline.ch> says: The acpi driver suspend/resume patches that went in recently caused a regression on my box (toshiba tecra 8000 laptop): after resume from swsusp the fan turns on keeping blowing cold air out of my notebook. before the patches, the fan was off and would only make noise when required. it's the same thing described in bugzilla.kernel.org #5000. the acpi suspend/resume patches or at least parts of them originate in this bug. now the last patch in the report (attach id 8438) actually fixes the problem - for me and the reporter. this is a trimmed down version of that patch.

During early MD setup (superblock reading), we don't have a personality yet. But the error-handling code tries to dereference mddev->pers. Fix. Acked-by:

The ioctl requires CAP_SYS_ADMIN, so sysfs should too. Note that we don't require CAP_SYS_ADMIN for reading attributes even though the ioctl does. There is no reason to limit the read access, and much of the information is already available via /proc/mdstat Cc: Chris Wright <chrisw@sous-sol.org> Signed-off-by:

The comment gives more details, but I didn't quite have the sequencing write, so there was room for races to leave bits unset in the on-disk bitmap for short periods of time. Signed-off-by:

When a device is unplugged, requests are moved from one or two (depending on whether a bitmap is in use) queues to the main request queue. So whenever requests are put on either of those queues, we should make sure the raid5 array is 'plugged'. However we don't. We currently plug the raid5 queue just before putting requests on queues, so there is room for a race. If something unplugs the queue at just the wrong time, requests will be left on the queue and nothing will want to unplug them. Normally something else will plug and unplug the queue fairly soon, but there is a risk that nothing will. Signed-off-by:

We introduced 'io_sectors' recently so we could count the sectors that causes io during resync separate from sectors which didn't cause IO - there can be a difference if a bitmap is being used to accelerate resync. However when a speed is reported, we find the number of sectors processed recently by subtracting an oldish io_sectors count from a current 'curr_resync' count. This is wrong because curr_resync counts all sectors, not just io sectors. So, add a field to mddev to store the curren io_sectors separately from curr_resync, and use that in the calculations.

When an array is started we start one or two threads (two if there is a reshape or recovery that needs to be completed). We currently start these *before* the array is completely set up and in particular before queue->queuedata is set. If the thread actually starts very quickly on another CPU, we can end up dereferencing queue->queuedata and oops. This patch also makes sure we don't try to start a recovery if a reshape is being restarted. Signed-off-by:

This has to be done in ->load_super, not ->validate_super Without this, hot-adding devices to an array doesn't always work right - though there is a work around in mdadm-2.5.2 to make this less of an issue. Signed-off-by:

I have reports of a problem with raid5 which turns out to be because the raid5 device gets stuck in a 'plugged' state. This shouldn't be able to happen as 3msec after it gets plugged it should get unplugged. However it happens none-the-less. This patch fixes the problem and is a reasonable thing to do, though it might hurt performance slightly in some cases. Until I can find the real problem, we should probably have this workaround in place. Signed-off-by:

screen_info.h doesn't have anything to do with the tty layer and shouldn't be included by tty.h. This patches removes the include and modifies all users to directly include screen_info.h. struct screen_info is mainly used to communicate with the console drivers in drivers/video/console. Note that this patch touches every arch and I have no way of testing it. If there is a mistake the worst thing that will happen is a compile error.

MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h allows all of the framebuffer and VT console drivers to remove their dependency on tty.h. [akpm@osdl.org: fix alpha build] Signed-off-by:

Use release_firmware() to free requested resources. According to Documentation/firmware_class/README the request_firmware() call should be followed by a release_firmware(). Some drivers do not however free the firmware previously allocated with request_firmware(). This patch tries to fix this by making sure that release_firmware() is used as expected. Signed-off-by:

As I was looking over the get_sb() changes, I stumbled across a little mistake in the documentation updates. Unless we're getting into an interesting new object-oriented realm, I doubt that get_sb() should really return "struct int"... Signed-off-by:

lockdep_map is embedded into every lock, which blows up data structure sizes all around the kernel. Reduce the class-cache to be for the default class only - that is used in 99.9% of the cases and even if we dont have a class cached, the lookup in the class-hash is lockless. This change reduces the per-lock dep_map overhead by 56 bytes on 64-bit platforms and by 28 bytes on 32-bit platforms. Signed-off-by:

Change the partition code in fs/partitions/check.c to initialize a newly detected partition's policy field with that of the containing block device (see patch below). My reasoning is that function set_disk_ro() in block/genhd.c modifies the policy field (read-only indicator) of a disk and all contained partitions. When a partition is detected after the call to set_disk_ro(), the policy field of this partition will currently not inherit the disk's policy field. This behavior poses a problem in cases where a block device can be 'logically de- and reactivated' like e.g. the s390 DASD driver because partition detection may run after the policy field has been modified.
