| * | ocfs2: Add statistics for the checksum and ecc operations. | Joel Becker | 2009-06-03 | 1 | -2/+27 |
| | | | | | | | | | | | | | | It would be nice to know how often we get checksum failures. Even better, how many of them we can fix with the single bit ecc. So, we add a statistics structure. The structure can be installed into debugfs wherever the user wants. For ocfs2, we'll put it in the superblock-specific debugfs directory and pass it down from our higher-level functions. The stats are only registered with debugfs when the filesystem supports metadata ecc. Signed-off-by: Joel Becker <joel.becker@oracle.com> | ||||
| * | ocfs2: Add the underlying blockcheck code. | Joel Becker | 2009-01-05 | 1 | -0/+82 |
| 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> | |||||
