UBI/UBIFS -f (--space-fixup) port to 2.6.30 kernel

Until recently, you cannot program a ubi image directly to nand flash for the following reason:

However, the 3.0 or newer kernel now offer a solution to allow you to do this using the -f (--space_fixup). Documentation: http://www.linux-mtd.infradead.org/f...ee_space_fixup

There is a UBIFS backport tree that goes back to the 2.6.32 kernel. However, I'm using the 2.6.30 kernel on an embedded board.

What steps would I take to patch my 2.6.30 kernel with one of the UBIFS backports? I'm assuming I would start with the 2.6.32 backport.

I would just get git://git.infradead.org/~dedekind/ubifs-v2.6.32.git and try to compare the code to your current kernel. If there are not too many changes you should be able to add the UBIFS patch easily.

There were enough changes to make me decide to upgrade to the 2.6.36 kernel. Thanks for your comments.
