the specific fix for this specific issue is probably the latter of the
following two:

Jan Kara (1):
      reiserfs: Fix use after free in journal teardown

Jeff Mahoney (1):

I can confirm that with 3.16.3 (which contains abovementioned, see comment #4,
reiserfs set of patches) the issue went out, I cannot reproduce it anymore.
