# Test our basic ability to work with different format versions.

# The current code being tested has a range of supported format
|
||||
# versions. For each of the older supported format versions we have a
|
||||
# git hash of the commit before the next greater version was introduced.
|
||||
# We build versions of the scoutfs utility and kernel module for the
|
||||
# last commit in tree that had a lesser supported version as its max
|
||||
# supported version. We use those binaries to test forward and back
|
||||
# compat as new and old code works with a persistent volume with a given
|
||||
# format version.
