There's desire to be able to customize parameters on a per-filesystem basis, which means we need a way to override the Kconfig defaults which are global. This also means the littlefs data structure cannot own the cache and lookahead buffers. Switch to using a macro to define the littlefs data structure. The default version uses the Kconfig constants. A custom one takes arguments providing the most likely partition-specific parameters. Finally the user is free to bypass the helper macros and set any parameters desired, though validation is limited and only present when CONFIG_DEBUG is enabled. Extend the test suite with a performance module, which confirms that these settings have an impact proportional to the log of changes to the cache or IO sizes. Signed-off-by: Peter A.
