UBIFS: copy file error

UBIFS: copy file error

[Nancy]

Hi,
   As you can see at last, copy file failed. I use ubifs-olpc-2.6.22 version.
   How can I make it right?

It may be this bug:

http://git.infradead.org/?p=users/dedekind/ubifs-2.6.git;a=commitdiff;h=313ae7e3fd310930971334cf7f735d272d6e797e

Otherwise try cherry picking the latest patches from:
