Yes, I'll add a regression test; binary files just don't work well in
patch sets, so I tend to put those in separate commits, for ease in
cherry picking.  Basically it's just a 100k ext2 filesystem with a
directory which happens to contain a name that begins with a open
parenthesis, i.e., "(oops)".

I was just going to accelerate getting 1.41.11 out the door, as
opposed to going to the effort of trying to deprecate 1.41.10.  In the
case of Debian, and Ubuntu, it's too late already since 1.41.10 has
already propagated out to bleeding-edge users.  So the only way to
pull it back would be to get a new release out the door, quickly...

I guess I can easily enough pull it from kernel.org and make
1.41.9 the default release to download on sourceforge.net.
