Module Name:    src

Modified Files:
        src/sys/fs/msdosfs: msdosfs_vfsops.c

Log Message:
Limit the minimum size of a disk sector to 512 bytes, to prevent memory
overflow on extremely low secsize. This normally conforms to the old standard
(for which there doesn't seem to be a clear spec). Since 2011, IDEMA's Advanced
Format standardizes it to 4k, so this change won't cause any trouble on
new devices.

Put the printf under DIAGNOSTIC temporarily to see if someone complains.

after a quick discussion on tech-kern
