Merge branch 'nd/unpack-trees-with-cache-tree'
The unpack_trees() API used in checking out a branch and merging walks one or more trees along with the index. When the cache-tree in the index tells us that we are walking a tree whose flattened contents is known (i.e. matches a span in the index), as linearly scanning a span in the index is much more efficient than having to open tree objects recursively and listing their entries, the walk can be optimized, which is done in this topic. * nd/unpack-trees-with-cache-tree: Document update for nd/unpack-trees-with-cache-tree cache-tree: verify valid cache-tree in the test suite unpack-trees: add missing cache invalidation unpack-trees: reuse (still valid) cache-tree from src_index unpack-trees: reduce malloc in cache-tree walk unpack-trees: optimize walking same trees with cache-tree unpack-trees: add performance tracing trace.h: support nested performance tracing
