It waits for an rcu grace period, after which all children kmem_caches should be deactivated. During the deactivation percpu_ref_kill() is called for non root kmem_cache refcounters, but it requires yet another rcu grace period to finish the transition to the atomic (dead) state. So in a rare case when not all children kmem_caches are destroyed at the moment when the root kmem_cache is about to be gone, we need to wait another rcu grace period before destroying the root kmem_cache. This issue can be triggered only with dynamically created kmem_caches which are used with memcg accounting. In this case per-memcg child kmem_caches are created. They are deactivated from the cgroup removing path. If the destruction of the root kmem_cache is racing with the removal of the cgroup (both are quite complicated multi-stage processes), the described issue can occur. The only known way to trigger it in the real life, is to unload some kernel module which creates a dedicated kmem_cache, used from different memory cgroups with GFP_ACCOUNT flag. If the unloading happens immediately after calling rmdir on the corresponding cgroup, there is some chance to trigger the issue.

After clear input from the RaspberryPi and Beagle communities, it has been established that prototyping, industrial automation and make communities strongly need this feature, and as we want people to use the character device, we have implemented the simple pull up/down interface for GPIO lines. This means we can specify that a (chip-specific) pull up/down resistor can be enabled, but does not offer fine-grained control such as cases where the resistance of the same pull resistor can be controlled (yet). - Introduce devm_fwnode_gpiod_get_index() and start to phase out the old symbol devm_fwnode_get_index_gpiod_from_child(). - A bit of documentation clean-up work. - Introduce a define for GPIO line directions and deploy it in all GPIO drivers in the drivers/gpio directory. - Add a special callback to populate pin ranges when cooperating with the pin control subsystem and registering ranges as part of adding a gpiolib driver and a gpio_irq_chip driver at the same time. This is also deployed in the Intel Merrifield driver. New drivers: - RDA Micro GPIO controller. - XGS-iproc GPIO driver.

In terms of diffstat the Qualcomm and Amlogic drivers are high up there because of all the clk data introcued by new drivers. The Nvidia Tegra driver had a lot of work done this cycle too to support suspend/resume and memory controllers. And the OMAP clk driver got proper clk and reset handling in place. Rounding out the patches are various updates to remove unused data, mark things static, correct incorrect data in drivers, etc. All the little things that improve drivers and maintain code health. I will point out that there's a patch in here for the GPIO clk driver, that almost nobody uses, which changes behavior and causes clk_set_rate() to try to change the GPIO gate clk's parent. Other than that things are fairly well SoC specific here.

There was one new xtensa defconfig in linux-next that enabled the system call this cycle and when asked about it the maintainer of the code replied that it was not enabled on purpose. As of today's linux-next tree that defconfig no longer enables the system call.

4afab1c | Yang Shi | 01 December 2019, 01:58:07 UTC | mm: shmem: use proper gfp flags for shmem_writepage() The shmem_writepage() uses GFP_ATOMIC to allocate swap cache. GFP_ATOMIC used to mean __GFP_HIGH, but now it means __GFP_HIGH | __GFP_ATOMIC | __GFP_KSWAPD_RECLAIM. However, shmem_writepage() should write out to swap only in response to memory pressure, so __GFP_KSWAPD_RECLAIM looks useless since the caller may be kswapd itself or in direct reclaim already. In addition, XArray node allocations from PF_MEMALLOC contexts could completely exhaust the page allocator, __GFP_NOMEMALLOC stops emergency reserves from being allocated. Here just copy the gfp flags used by add_to_swap(). Hugh: "a cleanup to make the two calls look the same when they don't need to be different (whereas the call from __read_swap_cache_async() rightly uses a lower priority gfp)".

The usage of CAP_SYS_PTRACE ensures compatibility with CRIU. Yet, if there are other users of non-cooperative userfaultfd that run without CAP_SYS_PTRACE, they would be broken :( Current implementation of UFFD_FEATURE_EVENT_FORK modifies the file descriptor table from the read() implementation of uffd, which may have security implications for unprivileged use of the userfaultfd.

So other checking on corresponding struct page is unnecessary too. So, if we check pte_protnone() firstly for each PTE, we can avoid unnecessary struct page accessing, so that reduce the cache footprint of NUMA balancing page table scanning. In the performance test of pmbench memory accessing benchmark with 80:20 read/write ratio and normal access address distribution on a 2 socket Intel server with Optance DC Persistent Memory, perf profiling shows that the autonuma page table scanning time reduces from 1.23% to 0.97% (that is, reduced 21%) with the patch.

bfe9d00 | Huang Ying | 01 December 2019, 01:57:28 UTC | autonuma: fix watermark checking in migrate_balanced_pgdat() When zone_watermark_ok() is called in migrate_balanced_pgdat() to check migration target node, the parameter classzone_idx (for requested zone) is specified as 0 (ZONE_DMA). But when allocating memory for autonuma in alloc_misplaced_dst_page(), the requested zone from GFP flags is ZONE_MOVABLE. That is, the requested zone is different. The size of lowmem_reserve for the different requested zone is different. And this may cause some issues. For example, in the zoneinfo of a test machine as below, Node 0, zone DMA32 pages free 61592 min 29 low 454 high 879 spanned 1044480 present 442306 managed 425921 protection: (0, 0, 62457, 62457, 62457) The free page number of ZONE_DMA32 is greater than "high watermark + lowmem_reserve[ZONE_DMA]", but less than "high watermark + lowmem_reserve[ZONE_MOVABLE]". And because __alloc_pages_node() in alloc_misplaced_dst_page() requests ZONE_MOVABLE, the zone_watermark_ok() on ZONE_DMA32 in migrate_balanced_pgdat() may always return true. So, autonuma may not stop even when memory pressure in node 0 is heavy. To fix the issue, ZONE_MOVABLE is used as parameter to call zone_watermark_ok() in migrate_balanced_pgdat(). This makes it same as requested zone in alloc_misplaced_dst_page(). So that migrate_balanced_pgdat() returns false when memory pressure is heavy.
