The default max-segments of indirect requests was 32, so IO operations with
bigger block size(>32*4k) would be split and make performance drop.
Nowadays backend device usually support 512k max_sectors_kb on desktop,

This patch series adds regulator-haptic device tree in rinato and monk boards.
The regulator-haptic has haptic motor and it is controlled by
voltage of regulator via force feedback framework.

For keeping handle per object, it allocates ZS_HANDLE_SIZE greater

Currently, zram's handle encodes object's location directly so
it makes hard to support migration/compaction.
This patch decouples handle and object via adding indirect layer.
For it, it allocates handle dynamically and returns it to user.
The handle is the address allocated by slab allocation so
For migration, we need to identify which object in zspage is
allocated so that we could migrate allocated(ie, used) object.
We could know it by iterating of freed objects in a zspage
but it's inefficient. Instead, this patch adds a tag(ie,
OBJ_ALLOCATED_TAG) in the head of each object(ie, handle) s
This patch provides core functions for migration of zsmalloc.
Migraion policy is simple as follows.
It searches source zspages from ZS_ALMOST_EMPTY and destination
zspages from ZS_ALMOST_FULL and try to move objects in source
zspage into destination zspages. If it is lack of destination
pages in Z
Curretly, zsmalloc regards a zspage as ZS_ALMOST_EMPTY if the zspage
has under 1/4 used objects(ie, fullness_threshold_frac).
It could make result in loose packing since zsmalloc migrates
only ZS_ALMOST_EMPTY zspage out.
This patch changes the rule so that zsmalloc makes zspage which has
above 3/4

Now that zsmalloc supports compaction, zram can use it.
For the first step, this patch exports compact knob via sysfs
so user can do compaction via "echo 1 > /sys/block/zram0/compact".

We don't need to call zram_meta_free under init_lock.
What we need to prevent race is setting NULL into zram->meta
(ie, init_done). This patch does it.

While creating a set of shielded CPUs, we passed cpuset_cpumask_can_shrink()
an empty cpumask (cur), and dl_bw_of(cpumask_any(cur)) made boom with it.

We stores handle on header of each allocated object so it
increases the size of each object by sizeof(unsigned long).
If zram stores 4096 bytes to zsmalloc(ie, bad compression),
zsmalloc needs 4104B-class to store the data with handle.
However, 4104B-class has 1-pages_per_zspage so wasted size by

During investigating compaction, fullness information of each class
and pages_per_zspage are helpful for investigating how compaction
works well on each size class.

Recently, there was issue about zsmalloc fragmentation and
I got a report from Juneho that new fork failed although there
are plenty of free pages in the system.
His investigation revealed zram is one of the culprit to make
heavy fragmentation so there was no more contiguous 16K page
for pgd to for
walk_page_range silently skips vma having VM_PFNMAP set,
which leads to undesirable behaviour at client end (who
called walk_page_range). For example for pagemap_read,
when no callbacks are called against VM_PFNMAP vma,
pagemap_read may prepare pagemap data for next virtual
address range at wrong i

Hi all,
Today's linux-next merge of the char-misc tree got a conflict in

and commit 73f0718e74e2 ("drivers: char: mem: Make /dev/mem an optional
