[PATCH 1/2] Allow to specify unsupported file systems

[Lukas Czerner]

As an addition to checking for supported file systems it would be nice
to be able to specify unsupported file system. In combination with
"generic" fs it can be useful. This patch adds that feature. For example
to set ext3 as an unsupported fs add "!ext3" into list.

Also specify ext3 and ex4 as unsupported file systems in 213 and 214
since those fs does not support fallocate. There may be others though.
