由 Ross Zwisler 提交于
Currently device_supports_dax() just checks to see if the QUEUE_FLAG_DAX flag is set on the device's request queue to decide whether or not the device supports filesystem DAX. Really we should be using bdev_dax_supported() like filesystems do at mount time. This performs other tests like checking to make sure the dax_direct_access() path works. We also explicitly clear QUEUE_FLAG_DAX on the DM device's request queue if any of the underlying devices do not support DAX. This makes the handling of QUEUE_FLAG_DAX consistent with the setting/clearing of most other flags in dm_table_set_restrictions(). Now that bdev_dax_supported() explicitly checks for QUEUE_FLAG_DAX, this will ensure that filesystems built upon DM devices will only be able to mount with DAX if all underlying devices also support DAX.

Add an explicit check for QUEUE_FLAG_DAX to __bdev_dax_supported(). This is needed for DM configurations where the first element in the dm-linear or dm-stripe target supports DAX, but other elements do not. Without this check __bdev_dax_supported() will pass for such devices, letting a filesystem on that device mount with the DAX option.

Memblock layout affects the pfn ranges covered by node/zone. Consider that we have a VM with 2 NUMA nodes and each node has 4GB memory, and the default (no memmap= given) memblock layout is like below: MEMBLOCK configuration: memory size = 0x00000001fff75c00 reserved size = 0x000000000300c000 memory.cnt = 0x4 memory[0x0] [0x0000000000001000-0x000000000009efff], 0x000000000009e000 bytes on node 0 flags: 0x0 memory[0x1] [0x0000000000100000-0x00000000bffd6fff], 0x00000000bfed7000 bytes on node 0 flags: 0x0 memory[0x2] [0x0000000100000000-0x000000013fffffff], 0x0000000040000000 bytes on node 0 flags: 0x0 memory[0x3] [0x0000000140000000-0x000000023fffffff], 0x0000000100000000 bytes on node 1 flags: 0x0 ... If you give memmap=1G!4G (so it just covers memory[0x2]), the range [0x100000000-0x13fffffff] is gone: MEMBLOCK configuration: memory size = 0x00000001bff75c00 reserved size = 0x000000000300c000 memory.cnt = 0x3 memory[0x0] [0x0000000000001000-0x000000000009efff], 0x000000000009e000 bytes on node 0 flags: 0x0 memory[0x1] [0x0000000000100000-0x00000000bffd6fff], 0x00000000bfed7000 bytes on node 0 flags: 0x0 memory[0x2] [0x0000000140000000-0x000000023fffffff], 0x0000000100000000 bytes on node 1 flags: 0x0 ... This causes shrinking node 0's pfn range because it is calculated by the address range of memblock.memory. So some of struct pages in the gap range are left uninitialized. We have a function zero_resv_unavail() which does zeroing the struct pages within the reserved unavailable range (i.e. memblock.memory && !memblock.reserved). This patch utilizes it to cover all unavailable ranges by putting them into memblock.reserved.

由 Mikulas Patocka 提交于
In kernel 4.17 I removed some code from dm-bufio that did slab cache merging (commit 21bb1327: "dm bufio: remove code that merges slab caches") - both slab and slub support merging caches with identical attributes, so dm-bufio now just calls kmem_cache_create and relies on implicit merging. This uncovered a bug in the slub subsystem - if we delete a cache and immediatelly create another cache with the same attributes, it fails because of duplicate filename in /sys/kernel/slab/. The slub subsystem offloads freeing the cache to a workqueue - and if we create the new cache before the workqueue runs, it complains because of duplicate filename in sysfs. This patch fixes the bug by moving the call of kobject_del from sysfs_slab_remove_workfn to shutdown_cache. kobject_del must be called while we hold slab_mutex - so that the sysfs entry is deleted before a cache with the same attributes could be created.

Revert commit c7f26ccf ("mm/vmstat.c: fix vmstat_update() preemption BUG"). Steven saw a "using smp_processor_id() in preemptible" message and added a preempt_disable() section around it to keep it quiet. This is not the right thing to do it does not fix the real problem. vmstat_update() is invoked by a kworker on a specific CPU. This worker it bound to this CPU. The name of the worker was "kworker/1:1" so it should have been a worker which was bound to CPU1. A worker which can run on any CPU would have a `u' before the first digit. smp_processor_id() can be used in a preempt-enabled region as long as the task is bound to a single CPU which is the case here. If it could run on an arbitrary CPU then this is the problem we have an should seek to resolve. Not only this smp_processor_id() must not be migrated to another CPU but also refresh_cpu_vm_stats() which might access wrong per-CPU variables. Not to mention that other code relies on the fact that such a worker runs on one specific CPU only. Therefore revert that commit and we should look instead what broke the affinity mask of the kworker.

The poll() changes were not well thought out, and completely unexplained. They also caused a huge performance regression, because "->poll()" was no longer a trivial file operation that just called down to the underlying file operations, but instead did at least two indirect calls. Indirect calls are sadly slow now with the Spectre mitigation, but the performance problem could at least be largely mitigated by changing the "->get_poll_head()" operation to just have a per-file-descriptor pointer to the poll head instead. That gets rid of one of the new indirections. But that doesn't fix the new complexity that is completely unwarranted for the regular case. The (undocumented) reason for the poll() changes was some alleged AIO poll race fixing, but we don't make the common case slower and more complex for some uncommon special case, so this all really needs way more explanations and most likely a fundamental redesign.

Currently, amdgpu_do_flip() spinlocks crtc->dev->event_lock and releases it only after committing updates to the stream. dc_commit_updates_for_stream() should be moved out of spinlock for the below reasons: 1. event_lock is supposed to protect access to acrct->pflip_status _only_ 2. dc_commit_updates_for_stream() has potential sleep's and also its not appropriate to be in an atomic state for such long sequences of code.

Support new VCN FW version naming convention: [31, 28] for VEP interface major version if applicable [27, 24] for decode interface major version [23, 20] for encode interface major version [19, 12] for encode interface minor version [11, 0] for firmware revision Bit 20-23, it is encode major and non-zero for new naming convention. This field is part of version minor and DRM_DISABLED_FLAG in old naming convention. Since the latest version minor is 0x5B and DRM_DISABLED_FLAG is zero in old naming convention, this field is always zero so far. These four bits are used to tell which naming convention is present.

It may not be the actual real stable mailing list address, but the stable scripts to actually pick up on the traditional way to mark stable patches. There are also reasons to explicitly avoid using the actual mailing list address, since security patches with embargo dates generally do want the stable marking, but don't want tools etc to mistakenly send the patch out to the mailing list early. So don't warn for things that are still actively used and explicitly supported. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
