ocfs2: Add the underlying blockcheck code.
This is the code that computes crc32 and ecc for ocfs2 metadata blocks. There are high-level functions that check whether the filesystem has the ecc feature, mid-level functions that work on a single block or array of buffer_heads, and the low-level ecc hamming code that can handle multiple buffers like crc32_le(). It's not hooked up to the filesystem yet. Signed-off-by: Joel Becker <joel.becker@oracle.com> Cc: Christoph Hellwig <hch@lst.de> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
