There's a missing semicolon 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.

Here's a crazy experiment for the broken version. Use an mmap-based tool to modify data on disk. Take a snapshot. The file in the snapshot and the file in the filesystem have different contents. Export and re-import the pool. They now have the same contents with the effects of the mmap having been reversed. I've also noticed that /proc/meminfo shows dirty data which will never go away until the pool is exported, though that's less thoroughly tested. |
I can't believe I missed that...

I think I broke github trying to combine both commits into a single one within the same pull request. Let's try this again with less fail. |
