mm: THP: introducing a fine-grained transparent hugepage technique for ARM64 architecture
Transparent hugepage (THP) is one of promise solutions to deal with
increased memory footprints, but it mostly focused on server-side
environments.
This patch claims that embedded systems also get benefits by using
THP to deal with increased but still small-sized memory footprints
in applications on the embedded system.
An ARM64 architecture featured a fine-grained hugepage which support
64KB sized hugepages while the size of commonly used hugepage is 2MB.
We used these two kinds of hugepages corresponding to required size
of virtual memory.
In this patch, we developed an eager-and-conservative policy. With
this policy, the kernel do not allow to allocate 2MB hugepages on
page faults to decrease enlarged page fault latencies. Instead, the
kernel allocates 64KB hugepages to deal with hugepage allocation.
Since 64KB hugepages require the smaller order pages than 2MB
hugepages, it does not severely affect to user-noticed memory latency
due to the memory management tasks such as memory compaction.
On the other hand, khugepaged makes both 64KB hugepages and 2MB
hugepages for both anonymous pages and file pages corresponding to
virtual memory sizes.
Moreover, our proposed finegrained THP (fTHP) supports hugepage
mappings on pages in CMA. Since pages in CMA already contiguous, fTHP
just allows hugepage mappings for 64KB or 2MB aligned memory areas.
The proposed method achieves upto 32% of throughput improvement
against Linux kernel with default THP that the system runs a read
workload in lmbench [1] when the buffer is fitted in the CPU
last-level-cache. For the large-sized buffer (bigger than 2MB),
the proposed method shows similar throughput to default THP in Linux
kernel.

device-mapper: Add dm-bow
dm-bow is a device mapper driver that allows to create a checkpoint on
the volume so that it is possible to restore the state if necessary.
This is needed to protect the ext4 partition during a system upgrade in
case of a power failure.

mm: LKSM: bug fix for kernel memory leak
For efficiency, LKSM cleans exited processes in a batched manner when it
finishes a scanning iteration. When it finds exited process while it is in
the scanning iteration, it just pends the mm_slot of the exited process to
the internal list.
On the other hend, when KSM daemon cleans mm_slots of exited processes, it
should care regions of exited processes to remove unreferenced lksm_region
objects.
Previously, most regions are maintained properly but only regions in "head"
of the exited process list does not be cleaned due to the buggy implementation.
At last, uncleaned objects are remained as unreferenced garbages.

mm: LKSM: new feature: use filter-based scanning to reduce scanning cost
LKSM_FILTER is a new feature which is intended to reduce the computation cost.
LKSM_FILTER exploits bitmap-based filters to skip scanning of unnecessary
pages. To this end, LKSM collects addresses of shared pages to make filters.
The rationale of LKSM_FILTER is that user-level programs share common runtime
framework and libraries. Because of that processes can have similar address
space layout. It means that if a page is merged with another page, the same
virtual address in different process can be merged with this merged page.
In this regard, KSM can use a single global filter to cover all sharable areas
in the system.
The challenge is caused by a secure construct of Linux kernel, namely ASLR.
ASLR enforces to have randomized address space for each process, and it
severely disrupts making a global filter.
To overcome this challenge, LKSM exploits two information: regions and offsets.
A region means the physically mapped area. Each process has its own VMAs but
they may mapped same files. A region means the original one.
An address space of a process is randomized in the unit of VMA. It means that
if pages are merged even in the different virtual addresses, there can be at
same offsets from individual VMAs.
LKSM leverages both regions and offsets to construct per-region filters.
By using per-region filters, LKSM could effectively reduce its scanning space
and also computation cost by up to 46% against previous version of LKSM at the
expense of somewhat sharing chances.

mm: LKSM: lightweight memory deduplication for embedded devices
Lightweight KSM (in short, LKSM) is a variant of KSM that is implemented in
a fully event-triggered manner. LKSM provides a memory deduplication facility
like vanilla KSM while it extremely reduces overhead.
Normally, LKSM is blocked and waits for incoming deduplication requests from
user-level process (e.g., resourced). When a user-level process submits
deduplication request via sysfs, LKSM performs requested-level of deduplication,
such as partial and full deduplications.
After that, LKSM is going to sleep again and waits for next request coming.
By doing so, LKSM mitigates side effects that impact on system performance,
for instance, occupying system resources such as CPU and incurring cache
pollutions.
