There are file system tests in LTP http://ltp.sourceforge.net/
including one called fsstress which is good for stress testing.

We would typically do power-off-recovery testing with fsstress
running.

There are also tests in mtd-utils:

	http://git.infradead.org/mtd-utils.git

We tend to run the integrity test as a basic test of whether things work,
but it is best if it can unmount the partition.

There are a bunch of tests in mtd-utils/tests/fs-tests that are run by
the run-all.sh script there.
