Chris Mason 0999df54f8 Btrfs: Verify checksums on tree blocks found without read_tree_block ... Checksums were only verified by btrfs_read_tree_block, which meant the functions to probe the page cache for blocks were not validating checksums. Normally this is fine because the buffers will only be in cache if they have already been validated. But, there is a window while the buffer is being read from disk where it could be up to date in the cache but not yet verified. This patch makes sure all buffers go through checksum verification before they are used. This is safer, and it prevents modification of buffers before they go through the csum code.
