[linux-mm-cc] Are there plans to get zRam out of the staging directory ?

[Mélodie]

Hello,

I have been a user of Compcache almost since the beginning. I had installed it to
Archlinux, when it came out in version 5.x, then with the version 6.x, and have been very
happy to use it and try it to a Debian minimal version I had installed to an old machine
as well.

I am astonished to still see in my dmesg :

"zram: module is from the staging directory, the quality is unknown, you have been
warned. " 

after... almost 5 years of development ?

I have been told at the #kernelnewbies chan that in the kernel 3.4.0-rc2
 (at least his 3.4.0-rc2 era git tree) still has the zram module source code in
drivers/staging.

I have seen that a few issues have been reported at the Compcache website project, so I
suppose some issues do exist...

I am only a simple user, and can only say in my computers : PC with either Intel or AMD
processors, single or dual-core, I didn't find any perverse effect. (Simple user, not
sophisticated benchmark here).

I have now been using it with a script meant to load it with the default recommended
configuration, making a device large as 1/4the of the available ram, one block device
only, in PCLinuxOS, since 2 years, on 3 different machines minimum, with an visible
improvement while using it : some virtual machines (in Virtualbox) which would not be
usable otherwise were usable, and some people have tested installing with a gui installer
needing some resource, on a machine having 128 MB ram, without the need to create a swap
file to compensate the lack of RAM memory.

So I will have a simple question here : what is missing to Compcache for it to be taken
out of the staging directory in the kernel tree ?

Many regards, and lots of thanks for this component !!
