[PATCH] mm: Make allocator take care of memoryless numa node (Xianting Tian) https://email@example.com
CPUs in powerpc like architecture could have no local memory. As the kernel code doesn’t care about it, this commit makes it to handle the case.
incoming (Andrew Morton) https://firstname.lastname@example.org
This is the pull request from Andrew Morton, the mm maintainer, for v5.10.
[PATCH v4 0/5] Speed up mremap on large regions (Kalesh Singh) https://email@example.com)
Repost fo the patch series.
[PATCH RFC v2] Opportunistic memory reclaim (Andrea Righi) https://firstname.lastname@example.org
This patch introduces new file under memcg, ‘memory.swap.reclaim’ that allow users to incur Reclaim even before the memory pressure happens, to help reducing system memory footprint and speed up hibernation/VM migration time, etc.
[PATCH v2 0/2] Add tracepoints around mmap_lock acquisition (Axel Rasmussen) https://email@example.com
This patchset adds tracepoints for mmap_lock to use that for analysis of the contention.
[RFC][PATCH 0/9] [v4][RESEND] Migrate Pages in lieu of discard (Dave Hansen) https://lkml.
[RFC PATCH v2 00/30] 1GB PUD THP support on x86_64 (Zi Yan) https://firstname.lastname@example.org
This patch adds support of 1GB THP using PUD.
[PATCH v4 00/11] KFENCE: A low-overhead sampling-based memory safety error detector (Marco Elver) https://email@example.com
The 4th version of the KFENCE patchset.
[PATCH 0/5] Speed up mremap on large regions (Kalesh Singh) https://firstname.lastname@example.org
This patchset optimizes mremap() by allowing memory regions to be able to mapped at PMD/PUD.
[PATCH] selftests/vm: 10x speedup for hmm-tests https://lkml.
DAMON contains a number of tests based on the kselftest and kunit in its patchset itself. As it is preferred to contain only tests having short runtime in kernel tree, I organized time consuming tests in a package and used it in my company only. Tests could be used as a good document and essential for contributors. For the reason, I promised I will make it open source in the last kernel summit talk (https://linuxplumbersconf.
[PATCH v3 00/10] KFENCE: A low-overhead sampling-based memory safety error detector (Marco Elver) https://email@example.com
The third version of KFENCE patchset is uploaded.
Machine lockups on extreme memory pressure (Shakeel Butt) https://lkml.kernel.org/r/CALvZod4FWLsV9byrKQojeus7tMDhHjQHFF5J_JpNsyB0HkaERA@mail.gmail.com
Shakeel reports a machine lockup due to extreme memory pressure. It’s locked up on memcg’s vmpressure sr_lock, which is irq-unsafe. And the lockup made in IRQ. He proposes a solution simply changing the lock with irq-safe one, but he also admits it’s not a maintainable solution.
[PATCH v14 0/5] KASAN-KUnit Integration (David Gow) https://firstname.lastname@example.org
The 14th patchset for the KASAN and KUnit integration. From the v13, compile warnings in test_kasan_module fixed.
[PATCH v2 00/10] KFENCE: A low-overhead sampling-based memory safety error detector (Marco Elver) https://email@example.com
The second version of the KFENCE posted.
[PATCH 1/2] fs: Add a filesystem flag for THPs (Matthew Wilcox) https://firstname.lastname@example.org
This patchset caches whether the backing filesystem support THP or not in an address space flags, so that the page cache can determine if it can send THP to the backing filesystem or not.
[PATCH RFC 00/10] KFENCE: A low-overhead sampling-based memory safety error detector (Marco Elver) https://email@example.com
This patchset introduces another kernel use-after-free detection infrastructure, called Kernel Electric-Fence (KFENCE). Unlike KASAN, this trades the performance for precision and as a result it incurs near zero performance overhead so that it can be enabled in the production.
[PATCH 00/11] Remove assumptions of THP size (Matthew Wilcox) https://firstname.lastname@example.org
Matthew is working for variable sized THP. For start of the work, this patchset changes the assumption that THP will be PMD size by introducing thp_nr_pages() and let the other VM code to use it.
[PATCH v9 0/3] introduce memory hinting API for external process (Minchan Kim) https://email@example.com
After the rejection, this patchset posted again. Linus’s opinion about dropping the task_struct to do_madvise and Christian’s comment regarding compat syscall entry has resolved.
And, this patchset merged in the ‘-mm’ tree again. Hopefully it will be merged in mainline by 5.10!
[PATCH v6 0/3] Anonymous VMA naming patches (Sumit Semwal) https://firstname.lastname@example.org
This is reposting of old patchset which Colin Cross sent before.
[RFC -V3 0/5] autonuma: Optimize memory placement for memory tiering system (Huang Ying) https://email@example.com
The third RFC of autonuma for help placing of data items on systems utilizing both DRAM and PMEM as different NUMA nodes.
Linux 5.9-rc3 https://lkml.kernel.org/r/CAHk-=wiD1yujm_WvWLYL7gZsWMvZyWMg1rfU7dWmnYYc3a7Gsg@mail.gmail.com
This week rc release is also quite normal. The ‘fallthought’ comment conversion made fairly evenly distributed changes. Torvalds says it was quite calm. Indeed, only one patchset got my interest this week.
PROBLEM: Long Workqueue delays. (Jim Baxter) https://firstname.lastname@example.org
Jim Baxter encountered 6.5 seconds delay due to long workqueue delay. He want to ask if this is normal or real problem.
[RFC PATCH 0/8] memcg: Enable fine-grained per process memory control (Waiman Long) https://email@example.com
The memory cgroup v2 start reclamation if the amount of the memory of the cgroup exceeds ‘memory.high’ and start OOM killing if if exceeds ‘memory.max’. Problem is, the OOM killer can kill any process.
