H A Dfile-item.cdiff 459931eca5f4b8c9ad259d07cc1ca49afed54804 Wed Dec 10 08:10:46 CST 2008 Chris Mason <chris.mason@oracle.com> Btrfs: Delete csum items when freeing extents

This finishes off the new checksumming code by removing csum items
for extents that are no longer in use.

The trick is doing it without racing because a single csum item may
hold csums for more than one extent. Extra checks are added to
btrfs_csum_file_blocks to make sure that we are using the correct
csum item after dropping locks.

A new btrfs_split_item is added to split a single csum item so it
can be split without dropping the leaf lock. This is used to
remove csum bytes from the middle of an item.
