zram: split memory-tracking and ac-time tracking

[ Upstream commit a7a0350583ba51d8cde6180bb51d704b89a3b29e ]

ZRAM_MEMORY_TRACKING enables two features:
- per-entry ac-time tracking
- debugfs interface

The latter one is the reason why memory-tracking depends on DEBUG_FS,
while the former one is used far beyond debugging these days. Namely
ac-time is used for fine grained writeback of idle entries (pages).

Move ac-time tracking under its own config option so that it can be
enabled (along with writeback) on systems without DEBUG_FS.

Merge tag 'mm-stable-2022-12-13' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull MM updates from Andrew Morton:

- More userfaultfs work from Peter Xu

- Several convert-to-folios series from Sidhartha Kumar and Huang Ying

- Some filemap cleanups from Vishal Moola

- David Hildenbrand added the ability to selftest anon memory COW
handling

- Some cpuset simplifications from Liu Shixin

- Addition of vmalloc tracing support by Uladzislau Rezki

- Some pagecache folioifications and simplifications from Matthew
Wilcox

- A pagemap cleanup from Kefeng Wang: we have VM_ACCESS_FLAGS, so use
it

- Miguel Ojeda contributed some cleanups for our use of the
__no_sanitize_thread__ gcc keyword.

This series should have been in the non-MM tree, my bad

- Naoya Horiguchi improved the interaction between memory poisoning and
memory section removal for huge pages

- DAMON cleanups and tuneups from SeongJae Park

- Tony Luck fixed the handling of COW faults against poisoned pages

- Peter Xu utilized the PTE marker code for handling swapin errors

- Hugh Dickins reworked compound page mapcount handling, simplifying it
and making it more efficient

- Removal of the autonuma savedwrite infrastructure from Nadav Amit and
David Hildenbrand

- zram support for multiple compression streams from Sergey Senozhatsky

- David Hildenbrand reworked the GUP code's R/O long-term pinning so
that drivers no longer need to use the FOLL_FORCE workaround which
didn't work very well anyway

- Mel Gorman altered the page allocator so that local IRQs can remnain
enabled during per-cpu page allocations

- Vishal Moola removed the try_to_release_page() wrapper

- Stefan Roesch added some per-BDI sysfs tunables which are used to
prevent network block devices from dirtying excessive amounts of
pagecache

- David Hildenbrand did some cleanup and repair work on KSM COW
breaking

- Nhat Pham and Johannes Weiner have implemented writeback in zswap's
zsmalloc backend

- Brian Foster has fixed a longstanding corner-case oddity in
file[map]_write_and_wait_range()

- sparse-vmemmap changes for MIPS, LoongArch and NIOS2 from Feiyang
Chen

- Shiyang Ruan has done some work on fsdax, to make its reflink mode
work better under xfstests. Better, but still not perfect

- Christoph Hellwig has removed the .writepage() method from several
filesystems. They only need .writepages()

- Yosry Ahmed wrote a series which fixes the memcg reclaim target
beancounting

- David Hildenbrand has fixed some of our MM selftests for 32-bit
machines

- Many singleton patches, as usual

zram: introduce recompress sysfs knob

Allow zram to recompress (using secondary compression streams)
pages.

Re-compression algorithms (we support up to 3 at this stage)
are selected via recomp_algorithm:

echo "algo=zstd priority=1" > /sys/block/zramX/recomp_algorithm

Please read documentation for more details.

We support several recompression modes:

1) IDLE pages recompression is activated by `idle` mode

echo "type=idle" > /sys/block/zram0/recompress

2) Since there may be many idle pages user-space may pass a size
threshold value (in bytes) and we will recompress pages only
of equal or greater size:

echo "threshold=888" > /sys/block/zram0/recompress

3) HUGE pages recompression is activated by `huge` mode

echo "type=huge" > /sys/block/zram0/recompress

4) HUGE_IDLE pages recompression is activated by `huge_idle` mode

echo "type=huge_idle" > /sys/block/zram0/recompress
