Support F2FS for microSD card

The fairly new FS designed for flash card. But it will probably mean upgrading the kernel to 3.8 or later...

The mentioned wikipedia page has a new link to the very good 40 min talk about flash and Linux filesystems from the linux.conf.au Jan/2015 in Auckland.
And I can also recommend reading this older LWN article.
The Jolla supported btrfs filesystem seems to be not bad for SD cards. But F2FS seems to be more optimised, like supporting the special handling of the FAT table area inside SD card controller firmware as mentioned in the talk.

There you go:

//EDIT: A bit of information to Jolla Oy: I used your kernel sources, then applied the patches from https://github.com/nowcomputing/f2fs-backports/tree/master/f2fs-base - then the patches from https://github.com/nowcomputing/f2fs-backports/tree/master/f2fs-for-3.5 and finally I cherry-picked these patches:
//EDIT²: Removed some unneeded patches from the list.

Is there f2fs support for Jolla C yet? I installed it from warehouse along with the bleeding edge sd-utils. The card won't mount. Am I doing sth. wrong?
uname -r shows:
3.10.49+0.0.52.2

That would be a useful feature.

Igorion ( 2014-03-04 15:09:42 +0300 )editExtremely good idea. It's clearly a very suitable file system for exactly this purpose.
GuSec ( 2014-03-04 18:11:01 +0300 )editIn general it would be nice if we got a newer kernel in one of the next updates, the newer kernels have some major battery and memory management updates that may benefit us too and of course f2fs
