Often mounting small filesystem with small logs will emit a warning such as: XFS (vdb): Invalid block length (0x2000) for buffer during log recovery. This causes tests to randomly fail because this output causes the clean filesystem checks on test completion to think the filesystem is inconsistent. The cause of the error is simply that log recovery is asking for a buffer size that is larger than the log when zeroing the tail. This is because the buffer size is rounded up, and if the right head and tail conditions exist then the buffer size can be larger than the log. Limit the variable size xlog_get_bp() callers to requesting buffers smaller than the log. Signed-off-by:
