Yeah -- coupled with sanity checking every existing file on the file system
at every remount, etc. And make them _real_ powerfaults, with an X10
controller or something. You get really weird behaviour out of flash chips
that way -- which we should deal with just fine.
If you're going to report any faults, it's best to do the testing with
CONFIG_JFFS2_FS_DEBUG=1 and _logging_ the kernel messages over a serial
port. But that of course slows down the test run. YMMV. A 230400 baud
serial console helps :)
