There's a missing semicolon and equals sign in the first hunk of this commit in config/kernel-bdi.m4. This results in the test always failing. The effects were noticed when rrdtool, a tool which modifies files by mmap() and msync(), would have data never get saved to disk in spite of the files working while the mounted filesystem remains mounted.
