[Ocfs2-devel] Bug in error handling

[Mark Fasheh]

At what point did you first see the error? Was it a 1st mount of a fresh
file system or just a normal mount? I assume the file system failed to mount
because of this error... Can you be more specific as to what Bad Things (TM)
were happening?  :) Did it crash or what?
