DHE fd23663000 Fix typos in commit b83e3e48c9
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.
