from hotplugged memory rather than only from main memory. Series "implement "memmap on memory" feature on s390". - More folio conversions from Matthew Wilcox in the series "Convert memcontrol charge moving to use folios" "mm: convert mm counter to take a folio" - Chengming Zhou has optimized zswap's rbtree locking, providing significant reductions in system time and modest but measurable reductions in overall runtimes. The series is "mm/zswap: optimize the scalability of zswap rb-tree". - Chengming Zhou has also provided the series "mm/zswap: optimize zswap lru list" which provides measurable runtime benefits in some swap-intensive situations. - And Chengming Zhou further optimizes zswap in the series "mm/zswap: optimize for dynamic zswap_pools". Measured improvements are modest. - zswap cleanups and simplifications from Yosry Ahmed in the series "mm: zswap: simplify zswap_swapoff()". - In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has contributed several DAX cleanups as well as adding a sysfs tunable to control the memmap_on_memory setting when the dax device is hotplugged as system memory. - Johannes Weiner has added the large series "mm: zswap: cleanups", which does that. - More DAMON work from SeongJae Park in the series "mm/damon: make DAMON debugfs interface deprecation unignorable" "selftests/damon: add more tests for core functionalities and corner cases" "Docs/mm/damon: misc readability improvements" "mm/damon: let DAMOS feeds and tame/auto-tune itself" - In the series "mm/mempolicy: weighted interleave mempolicy and sysfs extension" Rakie Kim has developed a new mempolicy interleaving policy wherein we allocate memory across nodes in a weighted fashion rather than uniformly.

Amongst other things, this opens up the use of third-party tools to parse and process out selftesting results. - Ryan Roberts has added fork()-time PTE batching of THP ptes in the series "mm/memory: optimize fork() with PTE-mapped THP". Mainly targeted at arm64, this significantly speeds up fork() when the process has a large number of pte-mapped folios. - David Hildenbrand also gets in on the THP pte batching game in his series "mm/memory: optimize unmap/zap with PTE-mapped THP". It implements batching during munmap() and other pte teardown situations. The microbenchmark improvements are nice. - And in the series "Transparent Contiguous PTEs for User Mappings" Ryan Roberts further utilizes arm's pte's contiguous bit ("contpte mappings"). Kernel build times on arm64 improved nicely. Ryan's series "Address some contpte nits" provides some followup work. - In the series "mm/hugetlb: Restore the reservation" Breno Leitao has fixed an obscure hugetlb race which was causing unnecessary page faults. He has also added a reproducer under the selftest code. - In the series "selftests/mm: Output cleanups for the compaction test", Mark Brown did what the title claims. - Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring". - Even more zswap material from Nhat Pham. The series "fix and extend zswap kselftests" does as claimed. - In the series "Introduce cpu_dcache_is_aliasing() to fix DAX regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in our handling of DAX on archiecctures which have virtually aliasing data caches. The arm architecture is the main beneficiary. - Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic improvements in worst-case mmap_lock hold times during certain userfaultfd operations. - Some page_owner enhancements and maintenance work from Oscar Salvador in his series "page_owner: print stacks and their outstanding allocations" "page_owner: Fixup and cleanup" - Uladzislau Rezki has contributed some vmalloc scalability improvements in his series "Mitigate a vmap lock contention".

Direct Access (DAX) can be used on memory-backed block devices.
|
|
If the block device supports DAX and the filesystem supports DAX,
|
|
then you can avoid using the pagecache to buffer I/Os. Turning
|
|
on this option will compile in support for DAX.
|
|
|
|
For a DAX device to support file system access it needs to have
|
|
struct pages. For the nfit based NVDIMMs this can be enabled
|
|
using the ndctl utility:
|
|
|
|
# ndctl create-namespace --force --reconfig=namespace0.0 \
|
|
--mode=fsdax --map=mem
|
|
|
|
See the 'create-namespace' man page for details on the overhead of
|
|
--map=mem:
|
|
https://docs.pmem.io/ndctl-user-guide/ndctl-man-pages/ndctl-create-namespace
|
|
|
|
For ndctl to work CONFIG_DEV_DAX needs to be enabled as well. For most
|
|
file systems DAX support needs to be manually enabled globally or
|
|
per-inode using a mount option as well. See the file documentation in
|
|
Documentation/filesystems/dax.rst for details.
|
|
|
|
If you do not have a block device that is capable of using this,
|

or if unsure, say N. Saying Y will increase the size of the kernel

tmpfs has historically used only inode numbers as wide as an unsigned

int. In some cases this can cause wraparound, potentially resulting

in multiple files with the same inode number on a single device. This

option makes tmpfs use the full width of ino_t by default, without

needing to specify the inode64 option when mounting.

|

But if a long-lived tmpfs is to be accessed by 32-bit applications so

ancient that opening a file larger than 2GiB fails with EINVAL, then
|

the INODE64 config option and inode64 mount option risk operations
|

failing with EOVERFLOW once 33-bit inode numbers are reached.
