[PATCH] md: remove inappropriate limits in md/bitmap configuration.
The kernel should not be imposing these policy limits: The time between bitmap updates should certainly be allowed to be more than 15 seconds, and if someone wants a bitmap chunk size in excess of 4MB, the kernel isn't the place to stop them.
