I'm confused - we already use xfs_fsr for low level testing of swapext functionality with carefully constructed donor file characteristics in xfs/227. What am I missing here? I don't see any problem with adding a specific command to run more controlled swapext tests, i just want to make sure I understand what xfs_fsr is not providing you with.
