Subject: 3.0 rc3 bug & warning fs/inode.c && fs/fs-writeback.c

from the just missed rc4 department:
I recieved this BUG last night on my laptop and it was shortly followed 
by a warning from the kernel. I doubt that I can reproduce this. It 
happened under a light load. I was doing some emailing using thunderbird 
(er.... icedove.....). let me know if there's anything I can do to help 
debug or if there's more info I can get that would help you figure out 
what went wrong.

Thanks,
Greg
