Hmm, which test is this?

Yes, quite a bit more than that.  One such test (which is used by
xfsqa test) is the fsstress proram, which is quite flexible.  You can
program different combinations of fallocate, direct I/O read/writes,
setxattr, buffered read/writes, symlinks, truncates, renames, etc..
The xfsqa suite will run fsstress in a number of different modes, but
that's not the only test program that it uses.  It also uses the fsx
program which exercises concurrent read/write/mmap operations, as well
as other programs to test acl support, noatime support, etc.

I make a point of running the regression test suite before pushing a
patch series to Linus; it makes me far more comfortable than I haven't
accidentally introduced some problem.

Yep.  You'll need to install a number of packages to compile it,
including libaio-dev, libattr1-dev, libacl1-dev, xfsprogs,
xfslibs-dev, etc.
