YAFFS2 not part of Linux Kernel

YAFFS2 not part of Linux Kernel

[Pietro Paolini]

Hello all,

reading docs and browsing internet I read that YAFFS2 is not merged in the Linux Kernel and that we should add it as a patch, the date is not write on that documents and I just tried to search YAFFS2 on the latest linux kernel source without relevant results. Then after a look on the www.yaffs.net I discovered a tutorial for merge it and I am sure, yes is not in the kernel tree.

On the website they said is under the GPL license and I don't understand, why is not merged in the Linux Kernel directly ?

It's just a curiosity, thanks in advance.
Pietro.

I don't know specifics, but when drbd decided to submit their code to the kernel for inclusion it took a tremendous amount of work on their part to get it into technically acceptable shape.

It's not like all they do is ask you if it's gpl.  They did deep into the code and make sure it meets the kernel devs standards.

You should ask the yaffs2 people about that as they are the only ones
who can actually answer it .....

Some time ago they tried to get it mainline, but they refused to make
the changes
the reviews requested. AFAIK yaffs stores some meta data in the NAND spare area,
which is a no-go.

Now we have UBI/UBIFS which makes yaffs2 obsolte anyway...
