So saying "The ioctl will succeed only when at least one output buffer is in the incoming queue." isn't true. Just drop the word 'only'. We cannot say that it will also work if no output buffers are queued as long as not all drivers are converted to vb2.

Most webcams covered by this driver are now supported by gspca. Nobody has the hardware to convert the remaining devices to gspca. This driver needs a major overhaul to have it conform to the latest frameworks and compliancy tests. Without hardware, however, this is next to impossible. Given the fact that this driver seems to be pretty much unused (it has been removed from Fedora several versions ago and nobody complained about that), we decided to drop this driver. This patch moves it to staging. Some time in 2014 we will drop it completely.

Limiting the number of backtraces being printed out can result in the user not seeing the information necessary to debug the issue. The hung_task_warnings sysctl controls this feature. This patch makes it possible for hung_task_warnings to accept a special value to print an unlimited number of backtraces when khungtaskd detects hung tasks. The special value is -1.

It contains 3 bits which indicate whether to enable accesses in user, kernel and hypervisor modes respectively to cause data breakpoint interrupts, plus one bit that enables both real mode and virtual mode accesses to cause interrupts. Currently, KVM sets DABRX to allow both kernel and user accesses to cause interrupts while in the guest. This adds support for the guest to specify other values for DABRX. PAPR defines a H_SET_XDABR hcall to allow the guest to set both DABR and DABRX with one call. This adds a real-mode implementation of H_SET_XDABR, which shares most of its code with the existing H_SET_DABR implementation. To support this, we add a per-vcpu field to store the DABRX value plus code to get and set it via the ONE_REG interface. For Linux guests to use this new hcall, userspace needs to add "hcall-xdabr" to the set of strings in the /chosen/hypertas-functions property in the device tree. If userspace does this and then migrates the guest to a host where the kernel doesn't include this patch, then userspace will need to implement H_SET_XDABR by writing the specified DABR value to the DABR using the ONE_REG interface. In that case, the old kernel will set DABRX to DABRX_USER | DABRX_KERNEL. That should still work correctly, at least for Linux guests, since Linux guests cope with getting data breakpoint interrupts in modes that weren't requested by just ignoring the interrupt, and Linux guests never set DABRX_BTI. The other thing this does is to make H_SET_DABR and H_SET_XDABR work on POWER8, which has the DAWR and DAWRX instead of DABR/X. Guests that know about POWER8 should use H_SET_MODE rather than H_SET_[X]DABR, but guests running in POWER7 compatibility mode will still use H_SET_[X]DABR. For them, this adds the logic to convert DABR/X values into DAWR/X values on POWER8. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de>

With commit a63d83f427fb ("oom: badness heuristic rewrite"), the OOM killer tries to avoid killing privileged tasks by subtracting 3% of overall memory (system or cgroup) from their per-task consumption. But as a result, all root tasks that consume less than 3% of overall memory are considered equal, and so it only takes 33+ privileged tasks pushing the system out of memory for the OOM killer to do something stupid and kill dhclient or other root-owned processes. For example, on a 32G machine it can't tell the difference between the 1M agetty and the 10G fork bomb member. The changelog describes this 3% boost as the equivalent to the global overcommit limit being 3% higher for privileged tasks, but this is not the same as discounting 3% of overall memory from _every privileged task individually_ during OOM selection. Replace the 3% of system memory bonus with a 3% of current memory usage bonus. By giving root tasks a bonus that is proportional to their actual size, they remain comparable even when relatively small. In the example above, the OOM killer will discount the 1M agetty's 256 badness points down to 179, and the 10G fork bomb's 262144 points down to 183500 points and make the right choice, instead of discounting both to 0 and killing agetty because it's first in the task list.

Of course, there are lots of product using zram in real practice. The major TV companys have used zram as swap since two years ago and recently our production team released android smart phone with zram which is used as swap, too and recently Android Kitkat start to use zram for small memory smart phone. And there was a report Google released their ChromeOS with zram, too and cyanogenmod have been used zram long time ago. And I heard some disto have used zram block device for tmpfs. In addition, I saw many report from many other peoples. For example, Lubuntu start to use it. The benefit of zram is very clear. With my experience, one of the benefit was to remove jitter of video application with backgroud memory pressure. It would be effect of efficient memory usage by compression but more issue is whether swap is there or not in the system. Recent mobile platforms have used JAVA so there are many anonymous pages. But embedded system normally are reluctant to use eMMC or SDCard as swap because there is wear-leveling and latency issues so if we do not use swap, it means we can't reclaim anoymous pages and at last, we could encounter OOM kill. :( Although we have real storage as swap, it was a problem, too. Because it sometime ends up making system very unresponsible caused by slow swap storage performance. Quote from Luigi on Google "Since Chrome OS was mentioned: the main reason why we don't use swap to a disk (rotating or SSD) is because it doesn't degrade gracefully and leads to a bad interactive experience. Generally we prefer to manage RAM at a higher level, by transparently killing and restarting processes. But we noticed that zram is fast enough to be competitive with the latter, and it lets us make more efficient use of the available RAM. " and he announced. http://www.spinics.net/lists/linux-mm/msg57717.html Other uses case is to use zram for block device. Zram is block device so anyone can format the block device and mount on it so some guys on the internet start zram as /var/tmp. http://forums.gentoo.org/viewtopic-t-838198-start-0.html Let's promote zram and enhance/maintain it instead of removing.

It was supposed to go in last round, but various issues pushed it to this release instead. The pull request contains: - Various smaller blk-mq fixes from different folks. Nothing major here, just minor fixes and cleanups. - Fix for a memory leak in the error path in the block ioctl code from Christian Engelmayer. - Header export fix from CaiZhiyong. - Finally the immutable biovec changes from Kent Overstreet. This enables some nice future work on making arbitrarily sized bios possible, and splitting more efficient. Related fixes to immutable bio_vecs: - dm-cache immutable fixup from Mike Snitzer. - btrfs immutable fixup from Muthu Kumar. - bio-integrity fix from Nic Bellinger, which is also going to stable" * 'for-3.14/core' of git://git.kernel.dk/linux-block: (44 commits) xtensa: fixup simdisk driver to work with immutable bio_vecs block/blk-mq-cpu.c: use hotcpu_notifier() blk-mq: for_each_* macro correctness block: Fix memory leak in rw_copy_check_uvector() handling bio-integrity: Fix bio_integrity_verify segment start bug block: remove unrelated header files and export symbol blk-mq: uses page->list incorrectly blk-mq: use __smp_call_function_single directly btrfs: fix missing increment of bi_remaining Revert "block: Warn and free bio if bi_end_io is not set" block: Warn and free bio if bi_end_io is not set blk-mq: fix initializing request's start time block: blk-mq: don't export blk_mq_free_queue() block: blk-mq: make blk_sync_queue support mq block: blk-mq: support draining mq queue dm cache: increment bi_remaining when bi_end_io is restored block: fixup for generic bio chaining block: Really silence spurious compiler warnings block: Silence spurious compiler warnings block: Kill bio_pair_split() ...

Various driver code still needs to be updated to not refer to the bvec directly before we can use this for interesting things, like efficient bio splitting.
