The bash stuff is similar to the dmflakey code, it just gives us functions to build and tear down a dm-log-writes target. We add a new LOGWRITES_DEV variable to take in the device we will use as the log and add checks for that. I've rigged up fsx to have an integrity check mode. Basically it works like it normally works, but when it fsync()'s it marks the log with a unique mark and dumps it's buffer to a file with the mark in the filename. I did this with a system() call simply because it was the fastest. I can link the device-mapper libraries and do it programatically if that would be preferred, but this works pretty well. The test itself just runs 200 ops and exits, then finds all of the good buffers in the directory we provided and replays up to the mark given, mounts the file system and compares the md5sum, unmounts and fsck's to check for metadata integrity. dm-log-writes will pretend to do discard and the replay tool will replay it properly depending on the underlying device, either by writing 0's or actually calling the discard ioctl, so I've enabled discard in the test for maximum fun. This test relies on the supporting userspace code I've written for dm-logs-writes.
