* 30.10.94 - added support for v2 filesystem

+ *
* 09.11.94 - Added test to prevent overwrite of mounted fs adapted
* from Theodore Ts'o's (tytso@athena.mit.edu) mke2fs
* program. (Daniel Quinlan, quinlan@yggdrasil.com)
*
* Usage: mkfs [-c | -l filename ] [-v] [-nXX] [-iXX] device [size-in-blocks]
*
- * -c for readablility checking (SLOW!)
+ * -c for readability checking (SLOW!)
* -l for getting a list of bad blocks from a file.
* -n for namelength (currently the kernel only uses 14 or 30)
* -i for number of inodes
* -v for v2 filesystem
*
* The device may be a block device or a image of one, but this isn't
- * enforced (but it's not much fun on a character device :-).
+ * enforced (but it's not much fun on a character device :-).
*
* Modified for BusyBox by Erik Andersen <andersen@debian.org> --
* removed getopt based parser and added a hand rolled one.
