This patch makes btrfsck check more things, including directory items, file extents, checksumming, inode link counts etc. The code for these checks is similar to the code verifies extent back references. The main difference is that shared tree blocks are treated specially. The partial checking results(unresolved references and/or errors) of shared sub-trees are cached. This avoids scanning the shared blocks several times. Thank you, Signed-off-by: Yan Zheng <zheng.yan@oracle.com>
