Subject: ocfs2: Add the underlying blockcheck code.
X-Git-Tag: v2.6.29-rc1~505^2~35
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=70ad1ba7b48364d758a112df0823edc5ca6632aa;p=pandora-kernel.git

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.
