Thanks for the fix. Same as your other reiserfs patch: no upstream commit (reiserfs was removed in 6.13) and no maintainer ack, so I can't queue a stable-only change for a removed subsystem on my own. If you can get subsystem review/ack, I'll reconsider. As before, exploitation requires mounting a crafted image. -- Thanks, Sasha
