	block size specification we start with is given as a power of two!).
	* ext2fs.h (block_size): Change type to unsigned int.
	(BLOCKSIZE_SCALE): Just use SBLOCK->s_log_block_size directly.

1999-09-04  Thomas Bushnell, BSG  <tb@mit.edu>

	(I don't know why; this is what Linux 2.3.14 does), skip tests for
	superblocks and descriptor blocks being free in bitmap.

	* dir.c: Replace `struct ext2_dir_entry' with `struct ext2_dir_entry_2'
