It's definitely worth a try to compile the master branch of the ext4
tree and see if it reproduces or not.
However, I suspect the problem will still be there. Based on the
commit which Markus has identified, I'm guessing it's a race between
the extents_status shrinker and writing into uninitialized region of
the file (since apprently compiling rtorrent with
--with-posix-fallocate is required).
Markus, how much memory do you have in your system? That may be the
other reason why I haven't been able to reproduce it to date; I had a
lot of free memory when I tried to reproduce the problem, so the slab
shrinker didn't engage.
