Sergey Senozhatsky adds infrastructure for passing algorithm-specific
parameters into zram. A single parameter `winbits' is implemented at
this time.
- The 5 patch series "memcg: nmi-safe kmem charging" from Shakeel Butt
makes memcg charging nmi-safe, which is required by BFP, which can
operate in NMI context.
- The 5 patch series "Some random fixes and cleanup to shmem" from
Kemeng Shi implements small fixes and cleanups in the shmem code.
- The 2 patch series "Skip mm selftests instead when kernel features are
not present" from Zi Yan fixes some issues in the MM selftest code.
- The 2 patch series "mm/damon: build-enable essential DAMON components
by default" from SeongJae Park reworks DAMON Kconfig to make it easier
to enable CONFIG_DAMON.
- The 2 patch series "sched/numa: add statistics of numa balance task
migration" from Libo Chen adds more info into sysfs and procfs files to
improve visibility into the NUMA balancer's task migration activity.
- The 4 patch series "selftests/mm: cow and gup_longterm cleanups" from
Mark Brown provides various updates to some of the MM selftests to make
them play better with the overall containing framework.
