I found this in my (Fedora 21) system today:
```
$ dnf whatprovides /usr/lib/systemd/system/zram.service
Using metadata from Tue May 19 15:25:37 2015 (9 days, 18:24:36 hours old)

```
What steps will reproduce the problem?
1. compiled zram builtin in kernel
2. boot the new kernel, initialize zram with:
echo $(( 64*1024*1024)) > /sys/block/zram0/disksize
3. mkswap /dev/zram0

```
> What steps will reproduce the problem?
1. Qemu + KSM + ZRAM = system hangs
2. when Zram works hard to compress pages
> What version of the product are you using? On what operating system?

I think this two should have better default values.
# cat /sys/block/zram0/queue/read_ahead_kb
128
# cat /sys/block/zram0/queue/rotational

rotationl should be 0, obviously.

Booting a `focal` suite kernel `5.15.0-48-generic` with `zram` bootflag ends up in a kernel panic:
```
$ qemu-system-x86_64 -kernel coinboot-vmlinuz-5.15.0-48-generic -initrd coinboot-initramfs-5.…

Need to add aufs in zram_init because it will integrate zram + tmp in ram + tmp in disk. Operating procedure:
1. Create a disk zram
2. Make in zram ext4
3. Make aufs = "ext4 in zram" + "dir in disk" a…

We've recently been discussing swap-on-zram again (see [systemd-oomd discussion](https://github.com/coreos/fedora-coreos-tracker/issues/840)).
In the past when we decided to wait we [also said we w…

- At least for Flaviramera
- the latest generator should be provisioned
- A trigger for recompression must be devised
- either
- simple cronjob(s) or
- systemd unit (s)

اونطور که توی ویکی آرچ گفته شده، [به طور پیشفرض Zswap فعاله](https://wiki.archlinux.org/title/Zswap). ولی توی صفحهٔ Zram گفته شده که [ترجیحا همزمان با هم از این دوتا استفاده نکنید](https://wiki.archl…
