Yes, very nice solution for developers.

Agree, but I would like this to be an option when building the kernel.
So distributions can choose to have this feature or not. I for example
use Ubuntu, and would be thrilled if the upstream Ubuntu kernel was
shipped with jffs2, jffs2.le and jffs2.be modules.
Perhaps just a define in Kconfig which will build the two extra
endianess specific modules.
