In Huawei we use jffs2 broadly in our products to support filesystem on raw
NOR flash and NAND flash, so fixing the bugs in jffs2 means a lot to us.

Although I have not read all of jffs2 code thoroughly, I had find and "fixed"
some bugs in jffs2 and I am willing to do any help in the jffs2 community. Maybe
we can start by testing and reviewing the pending patches in patch work ?
