[lvm-devel] [PATCH 15/16] test: Add test for fsadm resize command

[Lukas Czerner]

The tests exercises the fsadm "resize" functionality, by trying various
combinations of arguments and checking the desired results. It also
tries to create and resize volumes with various supported file systems,
checking the resulting size.
